Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF NORTHERN ARIZONA UNIVERSITY
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 11:
12. The device of claim 8, wherein, when the processor decodes the datastream using the wavelength and polarization of each of the incoming photons, the processor is configured to:
perform the polarization measurement on a first portion of the incoming photons according to the first measurement basis and on a second portion of the incoming photons according to the second measurement basis for each wavelength;
associate a first digit value with photons having the first wavelength that belong to the first portion and are polarized along the first polarization axis for the first wavelength according to the polarization measurement;
associate a second digit value with photons having the first wavelength that belong to the first portion and are polarized along the second polarization axis for the first wavelength according to the polarization measurement;
associate a third digit value with photons having the second wavelength that belong to the first portion and are polarized along the first polarization axis for the second wavelength according to the polarization measurement; and
provide the datastream and a key string that includes the first, second, and third digit values as inputs to a decoding function that outputs a decoded message.
