Streszczenie:
Quantum control theory is profitably reexamined from the perspective of quantum information, two results on the role of quantum information technology in quantum feedback control are presented and two quantum feedback control schemes, teleportation-based distant quantum feedback control and quantum feedback control with quantum cloning, are proposed. In the first feedback scheme, the output from the quantum system to be controlled is fed back into the distant actuator via teleportation to alter the dynamics of system. The result theoretically shows that it can accomplish some tasks such as distant feedback quantum control that Markovian or Bayesian quantum feedback can not complete. In the second feedback strategy, the design of quantum feedback control algorithms is separated into a state recognition step, which gives "on-off" signal to the actuator through recognizing some copies from the cloning machine, and a feedback (control) step using another copies of cloning machine. A compromise between information acquisition and measurement disturbance is established, and this strategy can perform some quantum control tasks with coherent feedback.

Streszczenie:
Quantum control strategy is discussed from the perspective of quantum information. First, the constraints imposed on quantum control by quantum theory are analyzed. Then some quantum control schemes based on quantum information are discussed, such as teleportation-based distant quantum control, quantum feedback control using quantum cloning and state recognition, quantum control based on measurement and Grover iteration. Finally, some applications of quantum control theory in quantum information and quantum computation such as quantum error correction coding, universality analysis of quantum computation, feedback-induced entanglement enhancement, etc., are presented and the potential applications of quantum control are also prospected.

Streszczenie:
Feedback control in quantum transport has been predicted to give rise to several interesting effects, among them quantum state stabilization and the realization of a mesoscopic Maxwell's daemon. These results were derived under the assumption that control operations on the system are affected instantaneously after the measurement of electronic jumps through it. In this contribution, I describe how to include a delay between detection and control operation in the master equation theory of feedback-controlled quantum transport. I investigate the consequences of delay for the state stabilization and Maxwell's daemon schemes. Furthermore, I describe how delay can be used as a tool to probe coherent oscillations of electrons within a transport system and how this formalism can be used to model finite detector bandwidth.

Streszczenie:
I study the rate at which information can be extracted from a finite-dimensional open quantum system using the quantum trajectory description of a continuous measurement. I derive the rate at which information is extracted for a measurement without any control; this sets the benchmark to which the subsequent control protocols are compared. Next I consider control protocols that increase the rate of information extraction. The first such protocol applies feedback so the state and the measurement basis are unbiased at all times. The use of unbiased bases means that this protocol is essentially quantum mechanical in nature. For observables with equally spaced eigenvalues, the “speed-up” in the information extraction afforded by unbiased basis feedback, is proportional to the square of the observed system’s Hilbert space. The second protocol considered optimally permutes the eigenvalues of the quantum state in the logical basis. As the measured observable and state commute at all times this protocol is essentially classical in nature. The speed-up provided by this protocol is also quadratic. The final protocol I consider is a new type of control. It merges open-loop quantum control and quantum filtering. This method also affords an improvement in the rate of information extraction.

Streszczenie:
The prospect of a universal quantum computer is alluring, yet formidable. Smaller scale quantum information processing, however, has been demonstrated. Quantum networks, interlinking flying and stationary qubits, and linear optical quantum computing (LOQC) are both good candidates for scaling up such computations. A strongly coupled atom-cavity system is a promising approach for applications in these fields, both as a node in a quantum network, and as a source of photons for LOQC. This thesis demonstrates the versatile capabilities of an atom-cavity system comprising a single 87Rb atom within a macroscopic high-finesse Fabry-Pérot cavity. It operates intermittently for periods of up to 100 μs, with single-photon repetition rates of 1 MHz and an intra-cavity production efficiency of up to 85%. Exploiting the long coherence time of around 500 ns, the photons are subdivided into d time bins, with arbitrary amplitudes and phases, thus encoding arbitrary qudits. High fidelity quantum logic is shown, operating a controlled-NOT gate integrated into a photonic chip with a classical fidelity of 95.9+1.4-1.7 %. Additionally, the generation of entanglement is verified and non-classical correlations between events separated by periods exceeding the travel time across the chip by three orders of magnitude are observed. Photonic quantum simulation is performed, using temporally encoded qudits to mimic the correlation statistics of both fermions and anyons, in addition to bosons. Finally measurement-based quantum feedback is demonstrated and used to actively control the routing of temporal qubits.

Streszczenie:
Quantum engineering has seen rapid growth in the past two decades. Physicists, mathematicians and engineers have been working in unison to control a number of diverse systems in the quantum regime. Quantum control involving feedback has become particularly topical, as using information gained from a system can lead to more stable operation of a control protocol. Quantum feedback can be split into two paradigms: measurement based feedback and coherent feedback. Although it is increasingly evident that retaining the coherence of the feedback signal provides an intrinsic advantage over measurement-based feedback, coherent feedback is still a new paradigm. In particular, there are a limited number of options for coherently estimating a state within a feedback loop. As a step towards better understanding and implementation of quantum feedback, this thesis reports on modelling, estimation and control of quantum systems. The first topic is physical realisability of a variety of quantum systems, especially finite level systems and their outgrowths. Bilinear quantum stochastic differential equations (QSDEs) have to be employed to characterise these systems, which is a significant complement to the previous work on linear QSDEs. In light of the fact that direct and indirect couplings play a vital role in quantum network and control, we also provide state-space models for different classes of coupled open quantum systems incorporating both bidirectional and directional interactions. The second topic is coherent observers and optimal filtering. It is well established that classically estimation using the Kalman filter can provide improved performance over direct feedback schemes, and similar demonstrations have been performed for measurement-based quantum feedback. In this thesis I present coherent observers, including least mean squares estimators, which are driven by the coherent output of a specified quantum plant and designed such that some subset of the observer and plant's expectation values converge in the asymptotic limit. Not only can estimators "observe" mean quantities of quantum plant, but also they can "estimate" quantum correlations such as entanglement. This is of much importance to coherent feedback design in the absence of measurement steps without loss of fidelity. Last but not least, several topics regarding stabilisation and control design of quantum systems are discussed in my thesis. To be specific, tools for quantum stability analysis (e.g. Lyapunov conditions) are provided. Both measurement-based feedback and coherent feedback control design are taken into account. A measurement-based optimal controller for opto-mechanical systems aimed at synchronising different mechanical modes is presented, which is application-oriented. Moreover, A general observer-based coherent feedback control framework is studied, and I demonstrate a pole-placement approach via coherent observers that can be applied to various scenarios.

Streszczenie:
Ces dernières années, les progrès réalisés dans le contrôle de l'interaction lumière-matière au niveau quantique ont conduit à de nombreuses avancées en optique quantique, en particulier dans l'étude de phénomènes quantiques fondamentaux, dans la conception de systèmes quantiques artificiels et dans les applications en information quantique. Il a notamment été possible d'augmenter considérablement l'intensité de l'interaction lumière-matière et de contrôler le couplage de systèmes quantiques à leur environnement, afin d'obtenir des états non conventionnels et fortement non classiques. Cependant, pour exploiter ces états quantiques en vue d'applications technologiques, il est crucial de pouvoir mesurer et contrôler ces systèmes avec précision. Dans ce contexte, ce travail de thèse est consacré à l'étude de nouveaux protocoles pour la mesure et le contrôle de systèmes quantiques dans lesquels des fortes interactions et des symétries particuliers conduisent à la génération d'états fortement non classiques. Nous nous intéressons dans un premier temps au régime de couplage ultra-fort de l'électrodynamique quantique en cavité (et de circuit). Plus précisément, l'état de fondamental n'est plus le vide standard, car il devient énergiquement favorable qu'il contienne des photons.Dans ce régime on peut même obtenir des chat de Schrödinger comme état fondamental.En revanche, pour assurer la conservation de l'énergie, les photons contenus dans ce vide exotique sont liés à la cavité et ne peuvent pas s'échapper dans l'environnement. Cela signifie qu'ils ne peuvent être mesurés par simple photodétection. Nous proposons dans ce travail un protocole spécialement conçu pour surmonter cette difficulté. Nous montrons qu'il est possible de déduire les propriétés photoniques de l'état fondamental à partir du déplacement de Lamb d'un système à deux niveaux auxiliaire.Les résonateurs optiques à paires de photons constituent une autre classe de systèmes dans lesquels la symétrie de parité conduit à des états quantiques non conventionnels. Grâce à "l'ingénierie de réservoir", il est aujourd'hui possible de contrôler l'interaction d'un système avec son environnement, de façon à le stabiliser dans des états quantiques particulièrement intéressants. En particulier, quand un résonateur (une cavité optique) est couplé à l'environnement par échange de paires de photons, il est possible de créer de chats de Schrödinger optiques dans la dynamique transitoire du système. Les corrélations quantiques de ces états sont par contre rapidement perdues en raison de la présence inévitable de dissipation à un photon. Protéger le système contre cette perturbation est le but du protocole de feedback basé sur la parité que nous présentons dans cette thèse
In recent years, the field of quantum optics has thrived thanks to the possibility of controlling light-matter interaction at the quantum level.This is relevant for the study of fundamental quantum phenomena, the generation of artificial quantum systems, and for quantum information applications.In particular, it has been possible to considerably increase the intensity of light-matter interaction and to shape the coupling of quantum systems to the environment, so to realise unconventional and highly nonclassical states.However, in order to exploit these quantum states for technological applications, the question of how to measure and control these systems is crucial.Our work is focused on proposing and exploring new protocols for the measurement and the control of quantum systems, in which strong interactions and peculiar symmetries lead to the generation of highly nonclassical states.The first situation that we consider is the ultrastrong coupling regime in cavity (circuit) quantum electrodynamics.In this regime, it becomes energetically favourable to have photons and atomic excitations in the ground state, that is no more represented by the standard vacuum.In particular, in case of parity symmetry, the ground state is given by a light-matter Schrödinger cat state.However, according to energy conservation, the photons contained in these exotic vacua are bound to the cavity, and cannot be emitted into the environment.This means that we can not explore and control them by simple photodetection.In our work we propose a protocol that is especially designed to overcome this issue.We show that we can infer the photonic properties of the ground state from the Lamb shift of an ancillary two-level system.Another class of systems in which the fundamental parity symmetry leads to very unconventional quantum states is given by two-photon driven-dissipative resonators.Thanks to the reservoir engineering, it is today possible to shape the interaction with the environment to stabilize the system in particularly interesting quantum states.When a resonator (an optical cavity) exchanges with the environment by pairs of photons, it has been possible to observe the presence of optical Schrödinger cat states in the transient dynamics of the system.However, the quantum correlations of these states quickly decays due to the unavoidable presence of one-photon dissipation.Protecting the system against this perturbation is the goal of the parity triggered feedback protocol that we present in this thesis

Streszczenie:
This thesis presents the theory of LQG (linear-quadratic-Gaussian) and Markovian feedback control for quantum systems. We devote Part I to a review of both classical and quantum feedback but with an emphasis on LQG and linear systems control. The language of classical stochastic control is that of probability theory and stochastic differential equations. Thus we first introduce the essential mathematics (within the context of measurement and control) such as the Kushner– Stratonovich and Langevin equations. We then specialize to linear classical systems and introduce traditional engineering principles such as stabilizing solutions of Riccati equations, controllability, certainty equivalence, and the like. The classical Kushner–Stratonovich and Langevin equations have well-known quantum analogues — the stochastic master equation and the quantum Langevin equation. These, and other relevant tools for doing quantum feedback control are reviewed. Subsequently the concepts of stabilizing solutions of Riccati equations, controllability, separation theorem, amongst other related notions are shown to be adaptable for quantum systems. An essential difference between quantum and classical feedback lies in the in-loop measurement. Quantum measurements induce quantum backaction, non-existent in classsical measurements. This means the measurement strength and strategy in a quantum feedback loop should be optimized for a given control objective. We illustrate each of these points with examples in LQG control. Part II is devoted to the theory of diffusive quantum measurements (measurements that have Gaussian distributed outcomes) and Markovian feedback control for nonlinear systems. A new and general representation of diffusive quantum measurements is derived. This representation is compared with an old representation (which we introduce in Part I) and shown to possess advantages over the old representation. We also propose a quantum optical scheme as a universal method for physically realizing diffusive quantum measurements. Our new representation of diffusive measurements is then applied to build a general theory of multiple-input multiple-output Markovian quantum feedback. Previously known results of Markovian feedback are reproduced as special cases of this more general framework.This work has not previously been submitted for a degree or diploma in any university. To the best of my knowledge and belief, the thesis contains no material previously published or written by another person except where due reference is made in the thesis itself.

Streszczenie:
This thesis considers two types of applications of quantum feedback control; feedback creation of nonclassical states of light, and controlling nonclassical properties of an ensemble of atoms. An electro-optical feedback loop will create an in-loop field with nonclassical photon statistics similar to squeezed light, resulting in fluorescence line-narrowing of a two-level atom coupled to such light. We extend this theory to study a three-level atom coupled to broadband squashed light, and confirm the two-level atom line-narrowing using a more realistic non-Markovian description of the feedback loop. The second type of application utilizes continuous QND measurement of atomic ensembles. If we measure the collective spin, then the system experiences conditional spin squeezing dependent on the measurement results. We show that feedback based on these results can continuously drive the system into the same conditioned state, resulting in deterministically reproducible spin squeezing. If we measure the atom number fluctuations of a BEC, then, due to the nonlinearity of atomic self interactions, this is also information about phase fluctuations. We show that feedback based on this information can greatly reduce the collisional broadening of the linewidth of an atom laser out-coupled from the condensate.

Streszczenie:
Dans cette thèse, nous nous intéressons à la stabilisation par rétroaction des systèmes quantiques ouverts soumis à des mesures imparfaites en temps continu. Tout d'abord, nous introduisons la théorie du filtrage quantique pour décrire l'évolution temporelle de l'opérateur de densité conditionnelle représentant un état quantique en interaction avec un environnement. Ceci est décrit par une équation différentielle stochastique à valeurs matricielles. Deuxièmement, nous étudions le comportement asymptotique des trajectoires quantiques associées à des systèmes de spin à N niveaux pour des états initiaux donnés, pour les cas avec et sans loi de rétroaction. Dans le cas sans loi de rétroaction, nous montrons la propriété de réduction de l'état quantique à vitesse exponentielle. Ensuite, nous fournissons des conditions suffisantes sur la loi de contrôle assurant une convergence presque sûre vers un état pur prédéterminé correspondant à un vecteur propre de l'opérateur de mesure. Troisièmement, nous étudions le comportement asymptotique des trajectoires de systèmes ouverts à plusieurs qubits pour des états initiaux donnés. Dans le cas sans loi de rétroaction, nous montrons la réduction exponentielle de l'état quantique pour les systèmes N-qubit avec deux canaux quantiques. Dans le cas particulier des systèmes à deux qubits, nous donnons des conditions suffisantes sur la loi de contrôle assurant la convergence asymptotique vers un état cible de Bell avec un canal quantique, et la convergence exponentielle presque sûre vers un état cible de Bell avec deux canaux quantiques. Ensuite, nous étudions le comportement asymptotique des trajectoires des systèmes quantiques ouverts de spin-1/2 avec les états initiaux inconnus soumis à des mesures imparfaites en temps continu, et nous fournissons des conditions suffisantes au contrôleur pour garantir la convergence de l'état estimé vers l'état quantique réel lorsque le temps tend vers l'infini. En conclusion, nous discutons de manière heuristique du problème de stabilisation exponentielle des systèmes de spin à N niveaux avec les états initiaux inconnus et nous proposons des lois de rétroaction candidates afin de stabiliser le système de manière exponentielle
In this thesis, we focus on the feedback stabilization of open quantum systems undergoing imperfect continuous-time measurements. First, we introduce the quantum filtering theory to obtain the time evolution of the conditional density operator representing a quantum state in interaction with an environment. This is described by a matrix-valued stochastic differential equation. Second, we study the asymptotic behavior of quantum trajectories associated with N-level quantum spin systems for given initial states, for the cases with and without feedback law. For the case without feedback, we show the exponential quantum state reduction. Then, we provide sufficient conditions on the feedback control law ensuring almost sure exponential convergence to a predetermined pure state corresponding to an eigenvector of the measurement operator. Third, we study the asymptotic behavior of trajectories of open multi-qubit systems for given initial states. For the case without feedback, we show the exponential quantum state reduction for N-qubit systems with two quantum channels. Then, we focus on the two-qubit systems, and provide sufficient conditions on the feedback control law ensuring asymptotic convergence to a target Bell state with one quantum channel, and almost sure exponential convergence to a target Bell state with two quantum channels. Next, we investigate the asymptotic behavior of trajectories of open quantum spin-1/2 systems with unknown initial states undergoing imperfect continuous-time measurements, and provide sufficient conditions on the controller to guarantee the convergence of the estimated state towards the actual quantum state when time goes to infinity. Finally, we discuss heuristically the exponential stabilization problem for N-level quantum spin systems with unknown initial states and propose candidate feedback laws to stabilize exponentially the system
