In order to model their intricate interplay with the laser-induced plasma processes, they have been implemented within the particle-in-cell code calder developed at CEA.

Such systems benefit from the collective enhancement of the interaction strength, while keeping the relaxation properties of a single emitter. Igor Diniz 1 AuthorId: Depending on the logical qubit state, the ancilla is resonantly or dispersively coupled to the resonator, leading to a large contrast in the transmitted microwave signal amplitude. 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.

Tuesday, August 21, – Studying this formalism is strongly motivated by recent proposals to use collections of emitters as quantum memories for individual excitations.

We find that their coherence depends crucially on the shape of the distribution and not only on its width. 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.

Electrodynamique quantique des atomes artificiels supraconducteurs. We discuss the influence of the emitters inhomogeneous broadening on the existence and on the coherence properties of the polaritonic peaks.

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.

In a third part, we analyze a prospective scheme of astrophysical interest, consisting in the collision between two dense pair plasmas produced quatique solid targets irradiated at Wcm-2 showing a quntique magnetic lamentation instability amplified by intense synchrotron emission.


This PhD thesis is concerned with the regime of extreme-intensity laser-matter interaction that should be accessed on upcoming multi-petawatt facilities e. Simulations show that this original method can be faster and have higher fidelity than methods currently used in circuit QED.
