Claim 0:
1. A system comprising:
a photon source configured to distribute photons in superposition states through a free-space or atmospheric communication channel;
an optical ground station configured to receive one or more of the photons from the photon source;
a communications hub, proximate to the optical ground station, configured to connect to a plurality of fiber optic links;
one or more quantum memory devices proximate to the optical ground station configured to send heralding signals upon reception of one or more of the photons; and
one or more computing devices configured to:
receive heralding signals from the one or more quantum memory devices indicating that two photons have been received at the one or more quantum memory devices via the photon source and via a given one of the plurality of fiber optic links connected to the communications hub, respectively; and
extend quantum entanglement from the free-space or atmospheric communication channel to the given one of the plurality of fiber optic links.
