This thesis focuses on two problems in circuit quantum electrodynamics.

Have you forgotten your login? On dit qu’elles sont hors couche [ 26 ]. We find that their coherence depends crucially on the shape of the distribution and not only on its width. Tuesday, August 21, – Igor Diniz 1 Details. Studying this formalism is strongly motivated by recent proposals to use collections of emitters as quantum memories for individual excitations.

Un positron absorbe un photon: Les diagrammes de Feynman semblent contredire cette assertion en montrant directement ce qui pourrait se passer au niveau atomique. Avec le temps, quanitque diagrammes sont devenus un langage permettant aux physiciens de parler de leurs calculs [ 15 ]. Dans les diagrammes de Feynman, les propagateurs sont les contributions quantiqje particules virtuelles. Such systems benefit from the collective enhancement of the interaction strength, while keeping the relaxation properties of a single emitter.

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.

Electrodynamique quantique des atomes artificiels supraconducteurs. Tuesday, April 9, – electrodunamique 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.

Diagramme de Feynman

This system supports a diamond-shape artificial atom where we define logical and ancilla qubits coupled through a cross-Kerr like term. Toute interaction plus complexe est une combinaison de ces six vertex [ 32 electrodynamoque.

We first investigate theoretically the coupling of a resonator to a continuous distribution of inhomogeneously broadened emitters. Selon l’orientation de ce vertex dans le temps on obtient six interactions possibles [ 31 ][ 15 ]:. Richard Feynman mettait en garde contre une utilisation figurative de ses diagrammes.

Quantum optics Quantum information Superconducting circuits Hybrid circuits Cavity quantum electrodynamics. The modeling is shown to be a powerful tool to obtain the properties of the spin ensembles coupled to a resonator.

Annihilation quark-antiquark, issus de deux hadrons. Tuesday, January 8, – 4: En revanche, tout ce qui se trouve au milieu, qui n’entre ni ne sort, n’est pas mesurable: Simulations show that this original method can be faster and have higher fidelity than methods currently used in circuit QED.

Igor Diniz 1 AuthorId: We discuss the influence of the emitters inhomogeneous broadening on the existence and on the coherence properties of the polaritonic peaks. Les gluons portant comme les quarks des charges de couleur contrairement aux photons qui sont neutres il existe electrovynamique vertex impliquant uniquement des gluons [ 33 ]:.
