Golz, Marcel. "Parametric quantum electrodynamics". Doctoral thesis, Humboldt-Universität zu Berlin, 2019. http://dx.doi.org/10.18452/19776.
Testo completoThis thesis is concerned with the study of Schwinger parametric Feynman integrals in quantum electrodynamics. Using a variety of tools from combinatorics and graph theory, significant simplification of the integrand is achieved. After a largely self-contained introduction to Feynman graphs and integrals, the derivation of the Schwinger parametric representation from the standard momentum space integrals is reviewed in full detail for both scalar theories and quantum electrodynamics. The derivatives needed to express Feynman integrals in quantum electrodynamics in their parametric version are found to contain new types of graph polynomials based on cycle and bond subgraphs. Then the tensor structure of quantum electrodynamics, products of Dirac matrices and their traces, is reduced to integer factors with a diagrammatic interpretation of their contraction. Specifically, chord diagrams with a particular colouring are used. This results in a parametric integrand that contains sums of products of cycle and bond polynomials over certain subsets of such chord diagrams. Further study of the polynomials occurring in the integrand reveals connections to other well-known graph polynomials, the Dodgson and spanning forest polynomials. This is used to prove an identity that expresses some of the very large sums over chord diagrams in a very concise form. In particular, this leads to cancellations that massively simplify the integrand.

Testo completoIn this thesis we investigate the interactions between ultracold atoms confined by a periodic potential and a mode of a high-finesse optical cavity whose wavelength is incommensurate with the potential periodicity. The atoms are driven by a probe laser and can scatter photons into the cavity field. When the von-Laue condition is not satisfied, there is no coherent emission into the cavity mode. We consider this situation and identify conditions for which different nonlinear optical processes can occur. We characterize the properties of the light when the system can either operate as a degenerate parametric amplifier or as a source of antibunched light. Moreover, we show that the stationary entanglement between the light and spinwavemodes of the array can be generated. In the second part we consider the regime in which the zero-point motions of the atoms become relevant in the dynamics of atom-photon interactions. Numerical calculations show that for large parameter regions, cavity backaction forces the atoms into clusters with a local checkerboard density distribution. The clusters are phase-locked to one another so as to maximize the number of intracavity photons.

Experiments in quantum optics have long been implemented with atoms in 3D free space or with atoms interacting with cavities. Over the past decade, the field of microwave quantum optics using superconducting circuits has gained a tremendous amount of attention. In particular, the confinement of photonic modes to 1D enables a new parameter regime of strong interactions between qubits and open waveguides. In these setups, known as waveguide quantum electrodynamics (WQED), superconducting qubits interact with a continuum of propagating photonic modes. In this thesis, we will explore the physics of WQED devices that consist of multiple qubits and their potential application to quantum information and simulation.

Testo completoCette thèse porte sur deux problèmes théoriques d'électrodynamique quantique en circuits supraconducteurs. Nous avons d'abord étudié les conditions d'obtention du couplage fort entre un résonateur et une distribution continue d'émetteurs élargie de façon inhomogène. Le développement de ce formalisme est fortement motivé par les récentes propositions d'utiliser des ensembles de degrés de liberté microscopiques pour réaliser des mémoires quantiques. En effet, ces systèmes bénéficient du couplage collectif au résonateur, tout en conservant les propriétés de relaxation d'un seul émetteur. Nous discutons l'influence de l'élargissement inhomogène sur l'existence et les propriétés de cohérence des pics polaritoniques obtenus dans le régime de couplage fort. Nous constatons que leur cohérence dépend de façon critique de la forme de la distribution et pas uniquement de sa largeur. En tenant compte de l'élargissement inhomogène, nous avons pu simuler avec une grande précision de nombreux résultats expérimentaux pionniers sur un ensemble de centres NV. La modélisation s'est révélée un outil puissant pour obtenir les propriétés des ensembles de spins couplés à un résonateur. Nous proposons également une méthode originale de mesure de l'état de qubits Josephson fondée sur un SQUID DC avec une inductance de boucle élevée. Ce système est décrit par un atome artificiel avec des niveaux d'énergie en forme de diamant où nous définissons les qubits logique et ancilla couplés entre eux par un terme Kerr croisé. En fonction de l'état du qubit logique, l'ancilla est couplée de manière résonante ou dispersive au résonateur, ce qui provoque un contraste important dans l'amplitude du signal micro-onde transmis par le résonateur. Les simulations montrent que cette méthode originale peut être plus rapide et peut aussi avoir une plus grande fidélité que les méthodes actuellement utilisées dans la communauté des circuits supraconducteurs

Testo completoJeantet, Adrien. "Cavity quantum electrodynamics with carbon nanotubes". Thesis, Sorbonne Paris Cité, 2017. http://www.theses.fr/2017USPCC010/document.
Testo completoCarbon nanotubes are extensively investigated for their amazing mechanical and electronic properties. Optically, they are excellent candidates for on-demand single-photon sources because they can be electrically excited and they can emit anti-bunched light at room temperature in the telecoms bands. However, their emission efficiency is low, its origins remain unclear and the spectral shape of their photoluminescence is complicated. In this work, we build an original setup combining a confocal microscope and a fiber based micro-cavity which is both spatially and spectrally tunable. With this device, we observed the rise of cavity quantum electrodynamics effects by analyzing the evolution of the dipole-cavity coupling as a function of the cavity volume. We obtained a strong acceleration of the spontaneous emission rate, due to Purcell factors above 100. The associated effective efficiency of the source reaches up to 50%, leading to a brightness of up to 10%, while keeping excellent anti-bunching features. We observe the effect of the cavity coupling as a function of the cavity detuning, and develop a model to account for emitters undergoing exciton-phonon coupling in the presence of a cavity. We show that our single-photon source is tunable on a range of frequencies more than a hundred times higher than the cavity spectral width, opening the way to extensive multiplexing. Further strengthening of the coupling may open the way to the very rich physics of one-dimensional cavity polaritons. And conversely, cavity polaritons could be a tool to understand better the diffusion, and localization properties of excitons in carbon nanotubes. Finally, the original setup build here is extremely versatile and could be used to coupled other types of emitters, such as nano-diamonds or molecules
