Patent ID: 7831048

Claim:
A system comprising an electronic computer for distribution of private information, the system comprising: a sending unit configured to encode at least one bit onto at least two photons and send the at least two photons to a receiving unit, the at least two photons comprising a first photon and a second photon, the at least two photons being entangled together, the at least one bit being encoded in a time delay between a propagation of the first photon and the second photon, the sending unit further configured to randomly select and impart a basis polarization on the at least two photons; and a receiving unit comprising an electronic computer configured to correctly detect the at least one bit on the at least two photons transmitted from the sending unit regardless of a basis polarization used to measure the at least two photons at the receiving unit, the receiving unit further configured to determine basis polarization information based on at least three received messages.
