The Effect of Emitters on Quantum State Transfer in Coupled Cavity Arrays

ORAL

Abstract

I will report an investigation into perfect quantum state transfer (QST) across coupled-cavity emitter arrays to provide a comprehensive understanding of the effects of system geometry and physical attributes on quantum state transfer as a function of time. By performing simulations with disordered emitter geometries and couplings to the cavity array, our group was able to determine the ways in which QST is degraded. This is unique as much of the existing literature on perfect QST and the effects of disorder focuses on cavity-only systems. We will show fidelity plots which illustrate the probability of transit from one side of the lattice to another for specific geometries, and also 'phase diagrams' which give the optimal QST fidelity as a function of the placement of a single emitter and its coupling to the cavity.
