【 摘 要 】

We present a scheme to generate entangled photons using nitrogen vacancy (NV) centers in diamond. We show how the long-lived nuclear spin in diamond can mediate entanglement between multiple photons, thereby increasing the length of the entangled photon string. With the proposed scheme one could generate both n-photon Greenberger-Horne-Zeilinger and cluster states. We present an experimental scheme realizing the same and estimate the rate of entanglement generation both in the presence and absence of a cavity.
