Abstract
Quantum networks based on nitrogen-vacancy (N-$V$) color centers in diamond will enable technology such as communication secured by the laws of nature, and blind quantum computation in the cloud. However, scaling to large distances and many nodes is hindered by the small coherent photon emission and collection from N-$V$ centers. By embedding a thin diamond membrane bearing coherent color centers into an open, tunable fiber-based optical microcavity, the authors demonstrate that the centers' emission can be enhanced in a fashion compatible with entanglement generation. This work is an important step toward employing N-$V$ centers in large-scale quantum networks with long coherence.
