Generation of entangled photon strings using NV centers in diamond

Abstract: We present a scheme to generate entangled photons using the 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 entangled photon string. With the proposed scheme one could generate both n-photon GHZ and cluster states. We present an experimental scheme realizing the same and estimating the rate of entanglement generation both in the presence and absence of a cavity.With controlled generation and manipulatio… Show more

“…Individual control and readout of nuclear spin qubits coupled to the electronic spin has been demonstrated [17]. Besides that, the control of two nuclear spins on an individual basis, generates entanglement of two 13 C nuclear spins at the first coordination shell of the vacancy [18] and mediate the entanglement between multiple photons [19]. Numerous quantum information protocols with NV centers have been previously discussed in the literature.…”
