Spin–photon entanglement in diamond for quantum optical networks

G. Dutt and M.U. Momeen,    University of Pittsburgh, USA


This chapter describes progress towards the realization of quantum networks through optical interconnections between isolated solid-state spin quantum bits (qubits) in diamond. Measurement-induced nonlinearity between photons emitted by two such qubits, and the resulting heralded entangled state, represents a key starting primitive in many theoretical protocols for quantum networks. This chapter first reviews the theory behind heralded entanglement generation, and then discusses the key requirements and some recent experiments that demonstrate all the ingredients necessary to achieve remote entanglement between ...
