Cavity Quantum Electrodynamics

This thesis focuses on electtodynamique problems in circuit quantum electrodynamics. These quantum electrodynamic processes, which until recently could only be explored on large-scale particle accelerators, can greatly alter the “standard” mechanisms of laser-plasma interaction, and therefore its overall energy budget. This PhD thesis is concerned with the regime of extreme-intensity laser-matter interaction that should be accessed on upcoming multi-petawatt facilities e.

Quantum electrodynamics in superconducting artificial atoms. Tuesday, January 8, – 4: Studying this formalism is strongly motivated by recent proposals to use collections of emitters as quantum memories for individual excitations.

In a second part, we consider positron generation in the collision between a GeV electron bunch issued from a laser-wake eld accelerator and a counterpropagating laser pulse. We first investigate theoretically the coupling of a resonator to a continuous distribution of inhomogeneously broadened emitters.


Mathieu Lobet 1, 2 AuthorId: Igor Diniz 1 AuthorId: Taking into account the inhomogeneous broadening allows to simulate with a great accuracy a number of pioneer experimental results on a ensemble of NV centers.

This system supports a diamond-shape artificial atom where we define logical and ancilla qubits coupled through a cross-Kerr like term. Have you forgotten your login?

Depending on the logical qubit state, the ancilla is resonantly or dispersively coupled to the resonator, leading to a large contrast quanitque the transmitted microwave signal amplitude.

In order to model their intricate interplay with the laser-induced plasma quwntique, they have been implemented within the particle-in-cell code calder developed at CEA. In a third part, we analyze a prospective scheme of astrophysical interest, consisting in the collision between two dense pair plasmas produced from solid targets irradiated at Wcm-2 showing a fast-growing magnetic lamentation instability amplified by intense synchrotron emission.


The modeling is shown to be a powerful tool to obtain the properties of the spin ensembles coupled to a resonator. Wednesday, May 11, – 1: Radiative and quantum electrodynamics effects in extreme intensity laser-matter interaction.

We find that their coherence depends crucially on the shape of the distribution and not only on its width. Such systems benefit from the collective enhancement of quantuque interaction strength, while keeping the relaxation properties of a single emitter. Simulations show that this original method can be faster and have higher fidelity than methods currently used in circuit QED.
