Full textFault tolerant quantum computation is a technique to perform reliable quantum computation using noisy components. In this context, quantum error correcting codes are used to keep the amount of errors under a sustainable threshold. One of the main problems of this field is to determine the minimum cost, in terms of memory and time, which is needed in order to transform an ideal quantum computation into a fault-tolerant one. In this PhD thesis, we show that the family of quantum expander codes and the small-set-flip decoder can be used in the construction of ref. [arXiv:1310.2984] to produce a fault-tolerant quantum circuit with constant space overhead. The error correcting code family and the decoder that we study has been introduced in ref. [arXiv:1504.00822] where an adversarial error model was examined. Based on the results of this article, we analyze quantum expander codes subjected to a stochastic error model which is relevant for fault-tolerant quantum computation [arXiv:1711.08351], [arXiv:1808.03821]. In addition, we show that the decoding algorithm can be parallelized to run in constant time. This is very relevant to prevent errors from accumulating while the decoding algorithm is running. Beyond the theoretical results described above, we perform a numerical analysis of quantum expander codes to measure their performance in practice [arXiv:1810.03681]. The error model used during these simulations generates X and Z type errors on the qubits with an independent and identically distributed probability distribution. Our results are promising because they reveal that these constant rate codes have a decent threshold and good finite length performance

Full textRecent years have seen a surge in the interest for non-standard computational models, inspired by physical, biological or chemical phenomena. The exact properties of some of these models have been a topic of somewhat heated discussion: what do they compute? And how fast do they compute? The stakes of these questions were heightened by the claim that these models would violate the accepted limits of computation, by violating the Church-Turing Thesis or the Extended Church-Turing Thesis. To answer these questions, the physical realizability of some of those models - or lack thereof - has often been put at the center of the argument. It thus seems that empirical considerations have been introduced into the very foundations of computability and computational complexity theory, both subjects that would have been previously considered purely a priori parts of logic and computer science. Consequently, this dissertation is dedicated to the following question: do computability and computational complexity theory rest on empirical foundations? If yes, what are these foundations? We will first examine the precise meaning of those limits of computation, and articulate a philosophical conception of computation able to make sense of this variety of models. We then answer the first question by the affirmative, through a careful examination of current debates around non-standard models. We show the various difficulties surrounding the second question, and study how they stem from the complex translation of computational concepts into physical limitations

Full textIn this thesis, we are interested in the theory of unconditional secure two-party computations of which Oblivious Transfer (OT) and Bit Commitment (BC) are the central primitives. On one hand, my works are inspired from Crépeau's et al. 's framework of building of OT protocol from noisy communication channels. The principle of this framework is to conceive, from noisy channels, an intermediate erasure model which is a variant of OT. We contributed to this framework by proposing a more general intermediate model, the Binary Symmetric Multi-Error-Rate Channel, which also can be built from noisy channels. With this intermediate model, we can build OT protocol from the noisy channels more effectively. In addition, we expose some case studies on emulating noisy models by a quantum nonorthogonal coding (QNOC) scheme which uses two non-orthogonal pure states for encoding two values of the classical bit. On the other hand, we revise the quantum model for general two-party protocols concerning classical and quantum computations and communications. We state that in the general model, a classical channel is inevitably macroscopic and its decoherence is so strong that quantum information is not accepted to be transfered on it. Thus, the quantum model for two-party protocols becomes three-party, including an environment of the channel. Indeed, with the faithful interpretation of general quantum two-party protocols in this three-party model, we reaffirm the no-go theorems of Mayers and Lo & Chau on the impossibilities of quantum OT, BC. In addion, we can go further to apply these negative results to protocols using some quantum trusted oracles, such as Coin-Flipping

Full textGraph States formalism consist in using graphs to model quantum states. This formalism allows us to use notion and tools of graph theory (e.g. flow, domination, probabilistic methods) in quantum information processing. Last years, this combinatorial modelisation had lead to many decisiv breakthroughs, in particular (i) in the comprehension of the quantum entranglement properties (ii) in very promising in term of physical implementation quantum calculus model, and (iii) in the analysis and construction of quantum cryptography protocols. The goal of this thesis is to study the graphic properties emerging of those quantum information processing problematics, especially for quantum simulation. In particular, the properties of causality and locality in graph states, by extanding for exemple the existing notion of causality flows to a notion integring the locality constraints, would allow new perspectives for the quantum system simulation using graphs states. Formal connections with noisy quantum cellular automata would emerge from this study

Full textThe theory of quantum computing lies at the very boundary between quantum physics and computer science. As such, both fields bring their own methods and mathematical tools to make quantum computing even richer. The present thesis attempts to reflect this specificity by addressing questions ranging from experimental physics to computational models. The goal is to provide novel ways of demonstrating quantum advantage. After a short introduction to basic notions of quantum mechanics, some computer science aspects are discussed. We describe the powerful formalism of quantum complexity classes and the concept of quantum computations based on continuous variables. We then translate the model of instantaneous quantum computing to continuous variables, which is experimentally appealing. The chapter concludes with a discussion on a hybrid protocol involving Grover’s algorithm in a quantum communication framework. The last part of the thesis is devoted to experimentally driven issues. A fundamental connection between the Hong-Ou-Mandel experiment and the Wigner function of two-photon states is derived and a verification protocol is designed accordingly. We then move to the field of superconducting circuits to discuss proposals for future experiments. We show how to use a flux qubit to manipulate a NV color center. We also describe how to use to probe the Rabi model in the ultra strong coupling regime using an additional weakly coupled qubit

Full textIn QMA, the quantum generalization of the complexity class NP, a quantum state is provided as a proof of a mathematical statement, and this quantum proof can be verified by a quantum algorithm. This complexity class has a very natural complete problem, the Local Hamiltonian problem. Inspired by Condensed Matters Physics, this problem concerns the groundstate energy of quantum systems. In this thesis, we study some problems related to QMA and to the Local Hamiltonian problem. First, we study the difference of power when classical or quantum proofs are provided to quantum verification algorithms. We propose an intermediate setting where the proof is a “simpler” quantum state, and we manage to prove that these simpler states are enough to solve all problems in QMA. From this result, we are able to present a new QMA-complete problem and we also study the one-sided error version of our new complexity class. Secondly, we propose the first relativistic verifiable delegation scheme for quantum computation. In this setting, a classical client delegates her quantumcomputation to two entangled servers who are allowed to communicate, but respecting the assumption that information cannot be propagated faster than speed of light. This protocol is achieved through a one-round two-prover game for the Local Hamiltonian problem where provers only need polynomial time quantum computation and access to copies of the groundstate of the Hamiltonian. Finally, we study the quantumPCP conjecture, which asks if all problems in QMA accept aproof systemwhere only a fewqubits of the proof are checked. Our result consists in proposing an extension of QPCP proof systems where the verifier is also provided an auxiliary classical proof. Based on this proof system, we propose a weaker version of QPCP conjecture. We then show that this new conjecture can be formulated as a Local Hamiltonian problem and also as a problem involving the maximum acceptance probability of multi-prover games. This is the first equivalence of a multi-prover game and some QPCP statement

Full textI want to realize an optimal theoretical model for quantum secret sharing protocols based on graph states. The main parameter of a threshold quantum secret sharing scheme is the size of the largest set of players that can not access the secret. Thus, my goal is to find a collection of protocols for which the value of this parameter is the smallest possible. I also study the links between quantum secret sharing protocols and families of curves in algebraic geometry
