Abstract
An apparatus includes a first pair of entanglement sources, a first Bell state measurement (BSM) device, at least one memory, a herald output, and at least one optical switch. The first pair of entanglement sources includes a first entanglement source and a second entanglement source configured to generate a first pair of entangled photons and a second pair of entangled photons at the same time. The first BSM device is connected with the first pair of entanglement sources to detect photons generated by each of the first entanglement source and the second entanglement source. The at least one memory is connected with the first pair of entanglement sources to store photons generated by the first entanglement source and the second entanglement source. The herald output includes an electronic circuit connected with the first BSM device for determining a number of photons detected by the first BSM device.
