Abstract

Entangled optical outputs are generated using one or more heralded entanglement sources, each comprising: first and second free-running entanglement sources, each providing a first (third) optical output comprising a quantum superposition of a pair of orthogonal optical modes, and a second (fourth) optical output comprising a quantum superposition of a pair of orthogonal optical modes; an optical module configured to perform an interferometric measurement based on optical interference between at least a portion of the first optical output and at least a portion of the third optical output, and to generate one or more detection signals based on the interferometric measurement in a series of time slots; and a trigger module configured to generate a trigger signal based on the one or more detection signals to indicate one or more time slots in which the second optical output and the fourth optical output are entangled with each other.
