Abstract:
1. A process for utilizing photons to communicate information through scattering media using at least one shared modulation sequence, the process comprising: generating photons from a light source in a first wavelength range; selectively modulating the photons using at least one shared modulation sequence to modify at least one property of a quantum state of certain of the photons to thereby encode the information in the form of a quantum communication photonic signal; transmitting said photonic signal in a scattering medium, the scattering media causing dispersion of the photons into multiple paths; receiving said scattered signal at a plurality of receiver locations; at least one of which is located such that no direct line-of-sight light path to the sender location exists; demodulating the photonic signal at synchronized time intervals, and measuring the at least one property of the quantum state of certain of the photons within the signal to recover the information being sent; whereby the information is sent from the sender to the receiver locations in non linear paths utilizing the natural scattering effects of the media to create the transmission paths for the photons wherein the at least one property of the quantum state of certain of the photons is substantially unaffected by the scattering media.
