Abstract
Systems and methods for dynamic locking of optical path times using entangled photons are provided. A system includes an optical source for generating bi-photons; tracer laser beam sources for generating tracer laser beams; telescopes that emit the tracer laser beams and the bi-photons to remote reflectors, each bi-photon traveling along an optical path in a pair of optical paths toward a corresponding remote reflector, wherein the telescopes receive reflected bi-photons from the remote reflectors; and communication links, wherein the optical source respectively communicates with first and second remote reflectors through a first and second communication link. Also, the optical source uses the tracer laser beams and the communication links to respectively point the bi-photons towards the remote reflectors. Moreover, the system includes an interferometer that provides information regarding detection of the reflected bi-photons, wherein the optical source uses the information to adjust optical path lengths to be substantially equal.
