A system and method for optical communication employing entangled photons. A modulator selectively extends the optical path length of one conjugate photon of each entangled photon pair, thereby incorporating a bit value in the entangled photon pair. The entangled photon pair is transmitted and passed through a spectrometer, which separates the photons according to their frequency and directs them to a coincidence counter. A decline in a curve of a number of coincidence counts plotted against conjugate photon frequency disparity is employed to extract the bit value.
