La construction d’un ordinateur quantique remettrait en cause la plupart des schémas à clef publique utilisés aujourd’hui. Par conséquent, il existe actuellement un effort de recherche important pour développer de nouveauxschémas cryptographiques post-quantique. En particulier, nous nous intéressons aux schémas post-quantiques dont la sécurité repose sur la dureté de la résolution de certains problèmes mathématiques tels que le problème PKP et leproblème HFE. Ce travail étudie d’abord la complexité de PKP. Et après une analyse approfondie des attaques connus sur PKP, nous avons pu mettre à jou

Abstract:

One emerging threat to Public Key Infrastructures is the possible development of large-scale quantum computers, which would be able to break the public-key cryptosystems used today. Several possibly post-quantum secure cryptographic algorithms have been proposed but so far they have not been used in many practical settings. The purpose of this thesis was to find post-quantum digital signature algorithms that might be suitable for use in Public Key Infrastructures today. To answer the research question, an extensive literature study was conducted where relevant algorithms were surveyed. Algorit

Abstract:

Avec la possibilité de l’existence d’un ordinateur quantique, les primitives cryptographiques basées sur la théorie des nombres risquent de devenir caduques. Il devient donc important de concevoir des schémas résistants à ce nouveau type de menaces. Les réseaux euclidiens et les codes correcteurs d’erreurs sont deux outils mathématiques permettant de construire des problèmes d’algèbre linéaire, pour lesquels il n’existe aujourd’hui pas d’algorithme quantique permettant d’accélérer significativement leur résolution. Dans cette thèse, nous proposons quatre primitives cryptographiques de ce type

Abstract:

This thesis studies continuous variable mixed states with the aim of better understanding the fundamental behaviour of quantum correlations in such states, as well as searching for applications of these correlations. I first investigate the interesting phenomenon of discord increase under local loss and explain the behaviour by considering the non-orthogonality of quantum states. I then explore the counter-intuitive result where entanglement can be created by a passive optical beamsplitter, even if the input states are classical, as long as the input states are part of a larger globally noncla

This thesis contains several theoretical studies on optomechanical systems, i.e. physical devices where mechanical degrees of freedom are coupled with optical cavity modes. This optomechanical interaction, mediated by radiation pressure, can be exploited for cooling and controlling mechanical resonators in a quantum regime. The goal of this thesis is to propose several new ideas for preparing meso- scopic mechanical systems (of the order of 10^15 atoms) into highly non-classical states. In particular we have shown new methods for preparing optomechani-cal pure states, squeezed states and enta

Full text

Abstract:

Generic Hamiltonian systems have a mixed phase space, in which regular and chaotic motion coexist. In the chaotic sea the classical transport is limited by partial barriers, which allow for a flux \Phi given by the corresponding turnstile area. Quantum mechanically the transport is suppressed if Planck's constant is large compared to the classical flux, h >> \Phi, while for h << \Phi classical transport is recovered. For the transition between these limiting cases there are many open questions, in particular concerning the correct scaling parameter and the width of the transition.

Abstract:

The conventional digital signature schemes widely used today may have their security threatened with the possibility of the rising of a large quantum computer. Moreover, such schemes are not entirely suitable for utilization on very constrained-resource platforms. Therefore, there is a need to look at alternatives that present reasonable security in the medium and long term, in addition to attaining acceptable performance when few resources are available. This work provides more efficient multivariate and hash-based post-quantum digital signatures and targets the deployment in scenarios like I

The research contained within this thesis concerns the detection, identification and effect of charge noise on quantum dot systems. In the first research chapter we study the cross correlation between pairs of exciton qubits subject to a common fluctuating charge environment, whose dynamics are solved using a transfer matrix approach. Our results show that we are able to discern features showing whether or not the charges interact with both quantum dots simultaneously i.e., form a correlated noise source. We find that qubits in a common charge environment display photon bunching, if both dots

We study the spatial distribution of molecular and atomic species generated by the filament in order to infer the relevant dynamics. We find evidence for a new impulsive vibrational excitation scheme which we introduce in this dissertation. Insight into the mechanisms of ionization is gained by consideration of the details of this process.

Among the most important of these models are the large extra dimensions model by Arkani-Hamed, Dimopoulos, and Dvali, the universal extra dimensions model, and models allowing right-handed neutrinos to propagate in the extra dimensions.

However in 1994, Peter Shor designed a quantum algorithm to resolve the prime factorization problem in polynomial time. Therefore, under the threat of quantum computer, the asymmetric-key system nowadays is not secure anymore.

Digital signatures are essential for the security of computer networks such as the Internet. For example, digital signatures are widely used to ensure the authenticity and integrity of updates for operating systems and other software applications. The security of the few practically used signature schemes is threatened by quantum computers. When large quantum computers are built, all currently used signature schemes will become insecure. It is therefore of extreme importance to develop alternative signature schemes that remain secure in the presence of quantum computers and which are able to c

<p>The 1D Wigner crystal is a long sought after strongly correlated quantum state. Here we present electronic transport data of asymmetric quantum point contacts (QPC) tuned to the spin-incoherent regime, which provides evidence for achieving the 1D Wigner state. Our result can be distinguished in several particularly noticeable ways. First, we utilize an asymmetric point contact geometry that is simple to fabricate and has not been studied previously. We are able to tune to the conductance anomalies simply by asymmetrically applying voltages to the gates. Second, we observe clear suppression
