Résumé :

We consider a system of multiple qubits without any quantum control. We show that one can mediate entanglement between different subsystems in a controlled way by adding a (locally) controlled auxiliary system of the same size that couples via an always-on, distant dependent interaction to the system qubits. Solely by changing the internal state of the control system, one can selectively couple it to selected qubits, and ultimately generate different kinds of entanglement within the system. This provides an alternative way for quantum control and quantum gates that does not rely on the ability to switch interactions on and off at will, and can serve as a locally controlled quantum switch where all entanglement patterns can be created. We demonstrate that such an approach also offers an increased error tolerance w.r.t. position fluctuations.

Résumé :

We propose a new scheme to generate multi-photon entanglement in two steps. First, we utilize a superconductor to create multi-quantum-dot entanglement; secondly, we use the input photon to transfer it into multi-photon entanglement. Moreover, the maximum probability for the swap of photon and quantum-dot qubits is close to unity for a single input Gaussian photon. More importantly, by mapping the multi-quantum-dot state into coherent states of oscillators, such as cavity modes, the multi-quantum-dot entanglement in our scheme can be protected from the decoherence induced by the noise. Thus, it is possible to generate more than eight spatially separated entangled photons in the realistic experimental conditions.

Résumé :

In this paper, we investigate the entanglement generation of n-qubit states in a model consisting of n independent qubits, each coupled to a harmonic oscillator which is in turn coupled to a bath of N additional harmonic oscillators with nearest-neighbor coupling. With analysis, we can find that the steady multipartite entanglement with different values can be generated after a long-time evolution for different sizes of the quantum system. Under weak coupling between the system and the harmonic oscillator, multipartite entanglement can monotonically increase from zero to a stable value. Under strong coupling, multipartite entanglement generation shows a speed-up increase accompanied by some oscillations as non-Markovian behavior. Our results imply that the strong coupling between the harmonic oscillator and the N additional harmonic oscillators, and the large size of the additional oscillators will enhance non-Markovian dynamics and make it take a very long time for the entanglement to reach a stable value. Meanwhile, the couplings between the additional harmonic oscillators and the decay rate of additional harmonic oscillators have almost no effect on the multipartite entanglement generation. Finally, the entanglement generation of the additional harmonic oscillators is also discussed.

Résumé :

In the framework of the theory of open systems based on completely positive quantum dynamical semigroups, we study the continuous variable entanglement for a system consisting of two independent harmonic oscillators interacting with a general environment. We solve the Kossakowski-Lindblad master equation for the time evolution of the considered system and describe the entanglement in terms of the covariance matrix for an arbitrary Gaussian input state. Using Peres–Simon necessary and sufficient criterion for separability of two-mode Gaussian states, we show that for certain values of diffusion and dissipation coefficients describing the environment, the state keeps for all times its initial type: separable or entangled. In other cases, entanglement generation, entanglement sudden death or a periodic collapse and revival of entanglement take place. We analyze also the time evolution of the logarithmic negativity, which characterizes the degree of entanglement of the quantum state.

Résumé :

Photons offer the potential to carry large amounts of information in their spectral, spatial, and polarisation degrees of freedom. While state-of-the-art classical communication systems routinely aim to maximize this information-carrying capacity via wavelength and spatial-mode division multiplexing, quantum systems based on multi-mode entanglement usually suffer from low state quality, long measurement times, and limited encoding capacity. At the same time, entanglement certification methods often rely on assumptions that compromise security. Here we show the certification of photonic high-dimensional entanglement in the transverse position-momentum degree-of-freedom with a record quality, measurement speed, and entanglement dimensionality, without making any assumptions about the state or channels. Using a tailored macro-pixel basis, precise spatial-mode measurements, and a modified entanglement witness, we demonstrate state fidelities of up to 94.4% in a 19-dimensional state-space, entanglement in up to 55 local dimensions, and an entanglement-of-formation of up to 4 ebits. Furthermore, our measurement times show an improvement of more than two orders of magnitude over previous state-of-the-art demonstrations. Our results pave the way for noise-robust quantum networks that saturate the information-carrying capacity of single photons.

Résumé :

Entanglement plays an important role in quantum communication, algorithms, and error correction. Schmidt coefficients are correlated to the eigenvalues of the reduced density matrix. These eigenvalues are used in von Neumann entropy to quantify the amount of the bipartite entanglement. In this paper, we map the Schmidt basis and the associated coefficients to quantum circuits to generate random quantum states. We also show that it is possible to adjust the entanglement between subsystems by changing the quantum gates corresponding to the Schmidt coefficients. In this manner, random quantum states with predefined bipartite entanglement amounts can be generated using random Schmidt basis. This provides a technique for generating equivalent quantum states for given weighted graph states, which are very useful in the study of entanglement, quantum computing, and quantum error correction.

Résumé :

Quantum entanglement is a key resource for performing quantum computing and building quantum communication networks. By injecting a microwave-optical dual-mode entanglement field into the system, as well as pumping the optical and microwave cavities, and by appropriately choosing the detuning relation between the pumping field and the modes, the paper shows that microwave-mechanics entanglement <i>E<sub>ab</sub></i>and magnon-optics entanglement <i>E<sub>cm</sub></i>can be generated simultaneously in the cavity opto-magnomechanics system, and the entanglement can be in a steady state. Specifically, the model is based on a hybrid quantum system of magnons, where a microwave-light entanglement generated by an optically pulsed superconducting electro-optical device through spontaneous parametric down-conversion process is injected as the intracavity field, and a blue-detuned microwave field is used to excite the magnon modes to produce magnon-phonon entanglement. By interacting with an optomechanical beam splitter and microwave-magnon state-swap interaction, steady microwave-mechanics entanglement <i>E<sub>ab</sub></i> and magnon-optics entanglement<i> E<sub>cm</sub></i> are successfully realized. The entanglement <i>E<sub>ab</sub></i>and <i>E<sub>cm</sub></i> in the system is analyzed using the logarithmic negativity. This paper mainly investigates the effect of several parameters of the system, such as environment temperature, coupling strength and dissipation rate, on the degree of entanglement. In particular, the entanglement <i>E<sub>ab</sub></i> and <i>E<sub>cm</sub></i> generated in this system can exist both simultaneously and individually. Especially when <i>g<sub>am</sub></i>=0, the entanglement <i>E<sub>ab</sub></i> and <i>E<sub>cm</sub></i> still exist. Moreover, directly injecting entangled microwave-light into the system can significantly enhance the robustness of the entanglement against temperature, which will have broad application prospects in quantum information processing in quantum networks and hybrid quantum systems. Notably, the entanglement <i>E<sub>ab</sub></i> and <i>E<sub>cm</sub></i> exist even at a temperature of 1.3K. The implications of our research has potential value for applications in the field of quantum information processing and quantum networks.

Résumé :

AbstractThe central technological appeal of quantum science resides in exploiting quantum effects, such as entanglement, for a variety of applications, including computing, communication and sensing1. The overarching challenge in these fields is to address, control and protect systems of many qubits against decoherence2. Against this backdrop, optical photons, naturally robust and easy to manipulate, represent ideal qubit carriers. However, the most successful technique so far for creating photonic entanglement3 is inherently probabilistic and, therefore, subject to severe scalability limitations. Here we report the implementation of a deterministic protocol4–6 for the creation of photonic entanglement with a single memory atom in a cavity7. We interleave controlled single-photon emissions with tailored atomic qubit rotations to efficiently grow Greenberger–Horne–Zeilinger (GHZ) states8 of up to 14 photons and linear cluster states9 of up to 12 photons with a fidelity lower bounded by 76(6)% and 56(4)%, respectively. Thanks to a source-to-detection efficiency of 43.18(7)% per photon, we measure these large states about once every minute, which is orders of magnitude faster than in any previous experiment3,10–13. In the future, this rate could be increased even further, the scheme could be extended to two atoms in a cavity14,15 or several sources could be quantum mechanically coupled16, to generate higher-dimensional cluster states17. Overcoming the limitations encountered by probabilistic schemes for photonic entanglement generation, our results may offer a way towards scalable measurement-based quantum computation18,19 and communication20,21.

Résumé :

We study the entanglement of two-qubit systems resulting from local interactions with spatially extended bosonic systems. Our results apply to the case where the initial state of the bosonic system is represented by a statistical mixture of states with fixed particle number. In particular, we derive and discuss necessary conditions to generate entanglement in the two-qubit system. We also study the scenario where the joint system is initially in its ground state and the interaction is switched on adiabatically. Using time independent perturbation theory and the adiabatic theorem, we show conditions under which the qubits become entangled as the joint system evolves into the ground state of the interacting theory

Résumé :

This dissertation consists of three sections. In the first section, we discuss the generation of arbitrary two-qubit entangled states and present three generation methods. The first method is based on the interaction of an atom with classical and quantized cavity fields. The second method is based on the interaction of two coupled two-level atoms with a laser field. In the last method, we use two spin-1/2 systems which interact with a tuned radio frequency pulse. Using those methods we have generated two qubit arbitrary entangled states which is widely used in quantum computing and quantum information. In the second section, we discuss a possible experimental implementation of quantum walk which is based on the passage of an atom through a high-Q cavity. The chirality is determined by the atomic states and the displacement is characterized by the photon number inside the cavity. Our scheme makes quantum walk possible in a cavity QED system and the results could be widely used on quantum computer. In the last section, we investigate the properties of teleporting an arbitrary superposition of entangled Dicke states of any number of atoms (qubits) between two distant cavities. We also studied teleporting continuous variables of an optical field. Teleportation of Dicke states relies on adiabatic passage using multiatom dark states in each cavity and a conditional detection of photons leaking out of both cavities. In the continuous variables teleportation scheme we first reformulate the protocol of quantum teleportation of arbitrary input optical field states in the density matrix form, and established the relation between the P-function of the input and output states. We then present a condition involving squeeze parameter and detection efficiency under which the P-function of the output state becomes the Q function of the input state such that any nonclassical features in the input state will be eliminated in the teleported state. Based on the research in this section we have made it possible of arbitrary atomic Dicke states teleportation from one cavity to another, and this teleortation will play an essential role in quantum communication. Since quantum properties is so important in quantum communication, the condition we give in this section to distinguish classical and quantum teleportation is also important.

Résumé :

Since its conception three decades ago, quantum computation has evolved from a theoretical construct into a variety of different physical implementations. In many implementations, quantum optics is a familiar tool for manipulating or transporting quantum information. Even as some individual components of quantum photonics technologies have shifted from lab-based setups into commercial products, effort is being devoted to the creation of quantum networks that would link these components together to form scalable computation devices. Here, I investigate optical phonons in bulk diamond, a previously overlooked system, as a physical resource for the construction of these devices. In this thesis, I measured the coherence properties of the diamond phonon, implemented a quantum memory write-read protocol using far-detuned Raman scattering, and entangled the phonon modes from two spatially separated pieces of diamonds in an adaptation of the seminal quantum repeater protocol proposed by Duan, Lukin, Cirac and Zoller (DLCZ). All of these experiments were conducted at room temperature with no optical pumping, using ultrafast broadband pulses (sub 100fs) - this is made possible by the unique physical properties of bulk diamond. Quantum memories and the creation of entangled states are key ingredients towards a working quantum network. By demonstrating that diamond can be used as a bulk solid in ambient conditions to implement these complex quantum interactions, I show that bulk diamond is a credible candidate for the construction of robust integrated nanophotonics chips capable of operating at THz frequencies. The quantum dynamics demonstrated here encompasses the motion of r-1016 atoms, which is several orders of magnitudes larger than the excitations created in other systems. This manifestation of quantum features at room temperature, in a regime that is traditionally described classical physics, is of fundamental interest, and highlights the need for further studies into the transition between quantum and classical physics.

Résumé :

Cette thèse présente de nouveaux protocoles pour les portes quantiques multi-qubits non locales et la génération d’intrication dans des systèmes où plusieurs émetteurs quantiques interagissent avec un mode bosonique partagé. Elle introduit les portes de phase géométrique et adiabatique, avec des expressions analytiques de l’infidélité dépendant du nombre de qubits et de la coopérativité. Pour deux qubits, elles forment un ensemble universel, tandis que dans les systèmes multi-qubits, elles permettent des portes déterministes pour la simulation quantique et la correction d’erreurs. Une contribution majeure est un protocole de détection optimisé par l’intrication, atteignant une haute précision de mesure grâce au contrôle optimal. La thèse explore aussi un mécanisme de blocage polaritonique en cavité pour la génération d’états W non locaux et de portes multi-qubits. Ces opérations déterministes, basées sur des excitations classiques de cavité et parfois des impulsions globales, offrent une base évolutive pour l’informatique quantique, la détection quantique et l'internet quantique de demain, en particulier pour les systèmes à atomes neutres
This thesis presents novel protocols for non-local multi-qubit quantum gates and entanglement generation in systems where multiple quantum emitters interact with a shared bosonic mode. It introduces the Geometric and Adiabatic Phase Gates, with closed-form infidelity expressions scaling with qubit number and cooperativity. For two qubits, these form a universal gate set, while in multi-qubit systems, they enable deterministic gates for quantum simulation and quantum error correction. A key contribution is an entanglement-enhanced sensing protocol that achieves high measurement precision via optimal control. The thesis also examines a cavity polariton blockade mechanism for non-local W-state generation and multi-qubit gates. These deterministic multi-qubit operations rely only on classical cavity drives and, in some cases, global qubit pulses, providing a scalable foundation for quantum computing, sensing, and the future quantum internet, especially for neutral atom systems

Résumé :

In this thesis, I report on how to use Single Photon Entanglement for generating certified quantum random numbers. Single Photon Entanglement is a particular type of entanglement which involves non-contextual correlations between two degrees of freedom of a single photon. In particular, here I consider momentum and polarization. The presence of the entanglement was validated using different attenuated coherent and incoherent sources of light by evaluating the Bell inequality, a well-known entanglement witness. Different non-idealities in the calculation of the inequality are discussed addressing them both theoretically and experimentally. Then, I discuss how to use the Single Photon Entanglement for generating certified quantum random numbers using a semi-device independent protocol. The protocol is based on a partial characterization of the experimental setup and the violation of the Bell's inequality. An analysis of the non-idealities of the devices employed in the experimental setup is also presented In the last part of the thesis, the integrated photonic version of the previously introduced experiments is discussed: first, it is presented how to generate single photon entangled states exploiting different degrees of freedom with respect to the bulk experiment. Second, I discuss how to perform an integrated test of the Bell's inequality.

Résumé :

Invisible Digital helps us makes sense of something we cannot see by presenting an innovative approach to digital images and digital culture. At its heart is a novel method for exploring software used in the creation of moving images as markers of converging cultural, organizational and technological influences. The three main case studies of Invisible Digital are the animated feature Moana (2016) and the computer games No Man’s Sky (2016) and Everything (2017). All three were created using procedural techniques: simulation software for Moana, and procedural content generation for No Man’s Sky and Everything. Production culture disclosures associated with procedural techniques often emphasize the influences of automated systems and their algorithms, making them ideal for a study that interrogates digital processes. The approach of Invisible Digital is informed by relational theories and the concept of entanglement based on materialist perspectives, combined with insights from work that more explicitly interrogates algorithms and algorithmic culture. Aylish Wood employs the notion of assemblages to introduce the concept of material-cultural narratives. Using this conceptual framework, she draws out material-cultural narratives for each case study to demonstrate what they reveal about software and digital culture. These analyses of software provide a widely applicable method through which moving image studies can contribute more fully to the wider and growing debates about algorithmic culture.

Résumé :

This is the first book-length study of the relationship between science fiction, the techno-scientific policies of independent India, and the global non-aligned movement that emerged as a response to Cold War and decolonization. Today, science-fiction writers are often used as government advisors on techno-scientific and defence policies. Such relationships between literature, policy and geo-politics have a long and complex history. Glimpses of this history can be seen in the case of the first generation of post-colonial Indian science fiction writers and their critical entanglements with both techno-scientific policies and the strategy of international non-alignment pursued by India’s first prime minister, Jawaharlal Nehru. This investigation reveals the surprisingly long and relatively unknown life of Indian science fiction, as well as the genre’s capacity to imagine alternative pathways to techno-scientific and geo-political developments that dominate our lives today.

Résumé :

This book shows how Seneca’s prose works offer both an illustration of and an invitation to philosophy as a way of life. In Seneca’s hands, the specificity of the philosopher’s social and historical location becomes generative of that way of life rather than an obstacle to be transcended. The social character of Senecan philosophical practice is brought to light through detailed examination of the ideas of solitude and independence in Seneca’s writing. Later chapters explore the relationship in Seneca’s works between the Socratic ideal of the examined life, on the one hand, and, on the other, some characteristically Roman social and political institutions: slavery, the philosophical school, and the commonwealth. Seneca emerges as a keen observer of philosophy’s social entanglements.

Résumé :

This book provides a succinct and accessible interpretation of the major event and ideas that have shaped U.S. foreign relations since the American Revolution—historical factors that now affect our current debates and commitments in the Middle East as well as Europe and Asia. American Foreign Relations since Independence explores the relationship of American policies to national interest and the limits of the nation's power, reinterpreting the nature and history of American foreign relations. The book brings together the collective knowledge of three generations of diplomatic historians to create a readily accessible introduction to the subject. The authors explicitly challenge and reject the perennial debates about isolationism versus internationalism, instead asserting that American foreign relations have been characterized by the permanent tension inherent in America's desire to engage with the world and its equally powerful determination to avoid "entanglement" in the world's troubles. This work is ideally suited as a resource for students of politics, international affairs, and history, and it will provide compelling insights for informed general readers.

Résumé :

AbstractIn this paper, we introduce a scaling method for the training of neural networks used for entanglement detection in Bin-Picking. In the Bin-Picking process of complex-shaped and chaotically stored objects, entangled workpieces are a common source of problems. It has been shown that deep neural networks, which are trained using supervised learning, can be used to detect entangled workpieces. However, this strategy requires time-consuming data generation and an additional training process when adapting to previously unseen geometries. To solve this problem, we analyze and compare several Meta-Learning techniques like Reptile, MAML and TAMS for their feasibility as a scaling method for the entanglement detection. These methods search for a strongly generalized model for entanglement detection by learning from the training process of various workpieces with different geometries. Using this generalized model for entanglement detection as initialization helps to increase the learning success with only few training epochs and reduces the required amount of data and therefore the setup effort significantly.

Résumé :

AbstractCurrent machine learning models are advertised to create complex, lifelike or painterly images from diverse inputs, such as text, sketches or photos. These models can be seen as a continuation to the recent years’ developments within artificial intelligence. In this article, I aim to broaden the discussion around machine learning, art, aesthetics and ethics. How do these algorithms change the way we create and think of images? How, then, does it change our aesthetics? Furthermore, as many of these models require substantial amounts of resources, I am interested in how cost, both ecological and economic, affects our comprehension and use of these technologies. The chapter builds on digital feminism and feminist phenomenology, and moves towards deepening the discussion around artificial intelligence, creativity and the arts.

Texte intégral

Résumé :

AbstractThis article provides a reading of archaeological traces in Beowulf that shows how the epic deals with and makes use of the notion of an always-already absent presence not in the singular, but in the plural. Through negotiating the notion of the trace, the epic produces a palimpsestic interplay between various levels and layers of absence-cum-presence—layers of temporality that are imagined, however, in very material terms. This layered, archaeological idea of temporality contributes to generating a complex notion of history. In particular, this article is interested in the ways in which, within the poem, the networks of traces associated with a given object may, in fact, help to constitute a specific concept of the historical event. In Beowulf, this essay argues, a historical event is characterized as such through the particular density and complexity of the entangled traces that mark it in a manner that resembles what Carolyn Dinshaw has called ‘multiple temporalities’. The epic thus conceives of an event in terms of a node that binds together a multiplicity of traces, and hence, a multiplicity of entangled temporalities.

Résumé :

AbstractThis chapter examines how the processes of human enhancement that have been brought about by the digital revolution (including AI and robotics, besides ICTs) have given rise to new social identities and relationships. The central question consists in asking how the Digital Technological Matrix, understood as a cultural code that supports artificial intelligence and related technologies, causes a hybridisation between the human and the non-human, and to what extent such hybridisation promotes or puts human dignity at risk. Hybridisation is defined here as entanglements and interchanges between digital machines, their ways of operating, and human elements in social practices. The issue is not whether AI or robots can assume human-like characteristics, but how they interact with humans and affect their social identities and relationships, thereby generating a new kind of society.

Texte intégral

Résumé :

We present and deploy our methodological and technological framework of Information Physical Quantum Technological Intelligence (IPQuTI), to empower next-generation mathematically robust, physically consistent, computationally efficient and operationally scalable synergies among models and data across multisectoral theoretical and applied workflows. Going beyond digital computing platforms, IPQuTI encompasses a richer basis alphabet of fundamental quantum states (information building blocks) and a high-order set of superposition and entanglement functionals (grammar) beyond the state of the art in quantum information itself. These are foundational core underneath our increased ability to encode, analyze, generate and simulate a broader physical language: one that is able to seamlessly treat complex high-dimensional data and model structures, interactions and operations with faster computational speed, higher robustness, physical consistency, information fidelity, spatiotemporal resolution and lead. For example, in the setting of ensemble operations, IPQuTI encapsulates an entire spatiotemporal system of events into a block operation as a coherent universe. Turning lengthy intense computational churning of approximate equations and massive datasets into a post-quantum spatiotemporal pulse of rich spatiotemporal diversity, spanning deterministic and stochastic synergies among models and data into a unified solution. With nonlinear geophysical applications in mind, IPQuTI is explored in key contexts of Data Assimilation, Data Fusion, Machine Learning, Predictability Investigation and Uncertainty Quantification. Firstly, to further optimize gold-standard state-of-art (SoA) solutions, providing them with a new efficient and robust platform to operate. Second, to overcome known SoA challenges, thereby contributing towards their methodological and practical upgrade. Third, to unveil novel features adding methodological and applied value to these areas, including handling sparse records, perturbations and extremes.

Texte intégral

Résumé :

This work seeks to unveil system dynamic predictability beyond existing data and model horizons, and beyond methodological paradigms in classical physics, machine learning and artificial intelligence, in order to increase awareness and preparedness to predict and tackle complexity and multi-hazards in a changing world, one where the coevolution among humans and nature has been reshaping the structure and functioning of our planet and the multiscale multidomain interactions within. For this purpose, we design and implement our next-generation Information Physical suite of Augmented Post-Quantum Synergistic Manifold Intelligence, harnessing the inherently physical nature of information from quantum fundamentals to augmented system dynamic intelligence for high-order complex system dynamics, including non-ergodic coevolution and emergence. Firstly, in the general physics of complex systems, from high-order quantum entanglement structures to fluid dynamical systems. Secondly, in tackling the emergence of new typologies of multi-hazards in coevolutionary multiscale multidomain spatiotemporal Earth System Dynamics, with special relevance to unprecedented challenges stemming from disruptive emerging features and in coevolutionary and synergistic interplay. These developments bring out a robust ability to predict the emergence of novel features and synergies elusive to prior record data or classical model structures, providing an augmented system dynamic intelligence to discern the complexity at play, unveiling extra predictability, spatiotemporal resolution and lead. Seamlessly integrated with our QITES and QuASI constellations, our latest advances empower researchers, practitioners and decision makers with augmented information capabilities crucial to avoid surprises and to improve readiness for novel structural dynamic features arising in our environment, in ways that are elusive to the classical systems theories, formulations, and products. In doing so, our novel solutions pave new avenues for strengthening predictability, preparedness and resilience.

Résumé :

Neuro-Quantum Cyber-Physical Intelligence (NQCPI) is hereby introduced, entailing a novel framework for nonlinear natural-based neural post-quantum information physics, along with novel advances in far-from-equilibrium thermodynamics and evolutionary cognition in post-quantum neurobiochemistry for next-generation information physical systems intelligence. NQCPI harnesses and operates with the higher-order nonlinear nature of previously elusive quantum behaviour, including in open chaotic dissipative systems in thermodynamically and magneto-electrodynamically disruptive conditions, such as in natural biological and environmental systems, thereby paving new pathways for post-quantum information technologies, including new paradigms for information encoding, encryption, transmission and security elusive to SoA post-quantum approaches. NQCPI further harnesses and operates with novel quantum properties including new classes of high-order emergence and entanglement structures, new neuro-quantum physical properties, with higher-order post-quantum-proof improvements in security, storage and relaying of information. It further empowers new capabilities to disarm security protocols of adversarial powers including those already at SoA quantum and post-quantum levels. This new technology is implemented into a novel coevolutionary system-of-systems seamlessly operating across classical, quantum, post-quantum cryptographic and key distribution approaches, thereby generalising them with added value whilst ensuring backward compatibility for seamless articulation with legacy and SoA protocols. Having demonstrated disruptive added value relative to post-quantum security, NQCPI is also tested and implemented in other quantum technological developments, ranging from sensing to communication and computation, in articulation with QITES (Quantum Information Technologies in the Earth Sciences), QuASI (Quantum Aerospace Systems Intelligence), AIPSI (Augmented Information Physical Systems Intelligence), and Synergistic Nonlinear Quantum Wave Intelligence Networks (SyNQ-WIN), respectively from Perdigão (2020, 2023) and Perdigão and Hall (2023, 2024).
