Patent ID: 7945168

Claim:
A process for utilizing entangled photon pairs to communicate information through scattering media using a predetermined modulation, the process comprising: generating entangled photon pairs; selectively modulating each photon of the entangled photon pairs at predetermined synchronized time intervals to modify the same property of the quantum state of both photons within the entangled photon pair to encode the information in the form of a quantum communication photonic signal; transmitting the quantum communication photonic signal in a scattering media, the scattering media causing dispersion of the entangled photon pairs into multiple paths; receiving said scattered signal at least one receiver location which is located such that no direct line-of-sight light path to the sender location exists; demodulating the photonic signal, and measuring the at least one property of the quantum state of the photons to recover the information being sent; whereby the information is sent from the sender to the at least one receiver location in non linear paths utilizing the natural scattering effects of the media to create the transmission paths for the photons wherein the property of the quantum states of the entangled photon pair is substantially unaffected by the scattering media.
