Compatibilité et non-localité
Autor: Loulidi, Faedi
Publikováno v: Quantum Physics [quant-ph]. Université Toulouse 3-Paul Sabatier, 2023. English. ⟨NNT : ⟩
Compatibility and non-locality are fundamental notions of quantum physics. Two POVMs are compatible if they are marginal from a third POVM. In the specific case of projective measurements, compatibility reduces to commutativity. Violations of Bell's

Spectroscopie de résonance de spin électronique des ions de terres rares dans la Scheelite détectée par fluorescence micro-ondes, à une température de l’ordre du millikelvin
Autor: Billaud, Eric
Publikováno v: Quantum Physics [quant-ph]. Université Paris-Saclay, 2023. English. ⟨NNT : 2023UPASP012⟩
Electron Spin Resonance (ESR) spectroscopy is a characterization method applicable to a wide variety of spin systems. This method, usually based on the Inductive Detection (ID) of spin echo, has a low sensitivity, restricting the detection to large s

Dynamique et traitement de l'information induits par réservoir dans des systèmes d'optique quantique
Autor: Li, Zejian
Publikováno v: Physics [physics]. Université Paris Cité, 2022. English. ⟨NNT : ⟩
This thesis is devoted to the study of reservoir-induced dynamics and reservoir computing in the context of quantum optics, structured along three major axes: (1) the dissipative dynamics of a quantum system in the presence of the environment (modele

Modélisation d'architectures de bits quantiques Si et Ge pour l'intégration à grande échelle
Autor: Martinez Diaz, Biel
Publikováno v: Physics [physics]. Université Grenoble Alpes [2020-..], 2022. English. ⟨NNT : 2022GRALY051⟩
Quantum computers rely on quantum two-level systems as memory units, the so-called qubits, and it is their quantum character what brings unique attributes that should enable to solve unaffordable problems with nowadays best classical computers. To th

Hamiltoniens locaux et information quantique en dimensions réduites
Autor: Boudreault, Christian
Cette thèse exploite les liens profonds entre la physique des systèmes quantiques locaux, les propriétés non locales de leurs états fondamentaux et le contenu en information de ces états. Les deux premiers chapitres sont consacrés à l’appli

Probability [math.PR]. Université de Lyon; Kyoto university, 2021. English. ⟨NNT : 2021LYSEN031⟩
This PhD lies at the intersection of Random Matrix Theory and Free Probability Theory. The connection between those two fields dates back to the early nineties with the work of Voiculescu who created the Theory of free probability. A probability theo

The construction of a quantum computer is an extremely challenging task, because the states of the quantum system used to carry out the computation are typically far too fragile. A necessary condition to build such a computer is to design a system in

Information quantique en variables continues temps-fréquence
Autor: Fabre, Nicolas
Publikováno v: Physics [physics]. Université de Paris, 2020. English. ⟨NNT : 2020UNIP7044⟩
This thesis tackles the time-frequency continuous variables degree of freedom encoding of single photons and examine the formal mathematical analogy with the quadrature continuous variables of the electromagnetic field. We define a new type of qubit
