Studying this formalism is strongly motivated by recent proposals to use collections of emitters as quantum memories for individual excitations. Dans les diagrammes de Feynman, les propagateurs sont les contributions des particules virtuelles. Espaces de noms Article Discussion.

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 des vertex impliquant uniquement des gluons [ 33 ]:.

En revanche, tout ce qui se trouve au milieu, qui n’entre ni ne sort, n’est pas mesurable: 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. Igor Diniz 1 AuthorId: Simulations show that this original method can be faster and have higher fidelity than methods currently used in circuit QED.

The modeling is shown to be a powerful tool to obtain the properties of the spin ensembles coupled to a resonator. Elwctrodynamique, January 8, – 4: Tuesday, August 21, – This system supports a diamond-shape artificial atom where we define logical and ancilla qubits coupled through a cross-Kerr like term. Richard Feynman mettait en garde contre une utilisation figurative de ses diagrammes.

This thesis focuses on two problems in circuit quantum electrodynamics.

Avec quntique temps, les diagrammes sont devenus un langage permettant aux physiciens de parler de leurs calculs [ 15 ]. Toute interaction plus complexe est une combinaison de ces six vertex [ 32 ].

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