Abstract
Quantum optical device authentication technologies are described herein. A first device includes an optical transmitter transmits a plurality of pulses to an optical receiver included on a second device. The optical pulses each have one of two non-orthogonal optical states. The optical receiver measures each of the pulses and the second device records a measured value of the optical state of each pulse. Subsequently, the second device transmits the measured values of the optical states of the pulses to the first device. The first device outputs an indication of whether the second device is authenticated based upon the measured values received from the second device and the optical states of the pulses transmitted by the optical transmitter.
