ABSTRACT:
Included in this disclosure is a quantum positioning system (QPS) that includes a corner cube reflector and a plurality of baselines. Each baseline may include an interferometer, which may include a photon source, a beam splitter, and a photon detector. The interferometer is configured for creating a bi-photon pair and initiating communication of the bi-photon pair with the corner cube reflector. Also included in the QPS is a positioning device configured to calculate a user's position.
