Abstract: Quantum networking systems and methods for routing entangled photons pairs are described herein. One quantum networking system includes entangled photon sources which generate entangled photons; optical output ports; a reconfigurable switching network connecting to the entangled photon sources and the output ports, which include a regular repeating structure of optical crossbar switches and interconnections for selectively routing individual ones of entangled photons pairs input to the network to and amongst the outputs; and a control module. The control module is configured to receive a request for entangled photons at the output ports; execute a routing algorithm to determine the state of the switches in the reconfigurable switching network to satisfy the request; and generate and transmit control signals to the switching network in order to set the states of the switches according to the executed routing algorithm. The reconfigurable switching network may be a Beneš or a banyan-type network architecture.
