Paper Abstract

Scalable quantum information processing using nitrogen-vacancy (NV) centers in diamond will be difficult without the ability to couple the centers to optical microcavities and waveguides. Here we present our preliminary result of coupling a single NV center in a nanoparticle to a silica microdisk at cryogenic temperatures. The cavity-coupled NV photoluminescence is coupled out of the cavity through a tapered fiber. Although the current system is limited by the spectral properties of the NV center and the Q of the cavity, efficient particle-cavity and cavity-waveguide coupling should lead to the realization of a "one-dimensional atom" as needed for CQED, enable single-shot electron-spin readout, and increase the probability of success in entanglement schemes based on single-photon detection.
