Abstract: An apparatus is disclosed herein. The apparatus comprises a non-linear photonic element for outputting a signal and idler photon pair. The apparatus further comprises a module configured to, based on receiving one or more control signals, controllably store photons and controllably output stored photons. The apparatus further comprises a detector arrangement comprising one or more detectors for detecting light. The module is further configured to receive at least one of the signal and idler photons of the pair. The module is further configured to at least partially store one of the signal or idler photons of the pair. The module is further configured to output the said at least partially stored signal or idler photon along an optical path towards the at least one detectors. The apparatus is configured to direct the other of the signal or idler photon towards the detector arrangement.

Abstract: An apparatus has a plurality of photonic elements. At least two photonic elements forming a cavity. At least one photonic element receives first electromagnetic radiation from outside the cavity and transmits the first electromagnetic radiation into the photonic cavity. At least one photonic element receives second electromagnetic radiation from outside the cavity and transmits the second radiation into the photonic cavity. A photonic memory disposed in the cavity comprises an atomic system that: receives a photon field of first radiation; receives second radiation; stores at least a portion of the field of the photon in the atomic system via an atomic transition using the photon and the received second radiation; emits the stored portion of the photon upon receiving third electromagnetic radiation. The apparatus directs the photon into the photonic memory, after being reflected into the photonic cavity by at least one of the photonic elements; and outputs the emitted portion of the field into the cavity. The apparatus controls the photon flux density of the third electromagnetic radiation to control the superposition of the said stored field portion.
