Abstract
The disclosure relates to secured wireless communications. A sender device emits randomly photons in a first polarization, a second polarization and a third polarization without aligning a polarization system in a plane perpendicular to the first and second polarizations with a recipient device. The recipient device is adapted for detection of events in association with six polarizations. The recipient device selects randomly polarization basis for measurement of the received photons. Information of detected events in association with three basis is communicated to the sender device. The information from the recipient device and information stored in the sender device is processed to determine events where same polarization basis was used by the sender device and the recipient device.
