OPTICAL-BASED, SELF-AUTHENTICATING QUANTUM RANDOM NUMBER GENERATORS

摘要

Various embodiments of the present invention are directed to methods and systems for generating random numbers. In one embodiment, a quantum random number generator (1100, 1200, 1300) comprises: a state generator (1102) configured to generate a quamtum system in a coherent state; a polarization states analyzer (1104) configured to project the quantum system onto one of four different polarization states, and detect each of the four different ploarization states; a raw bit generator (1106) configured to convert the quantum system into a single photon and detect the single photon in either a first polarization state that corresponds to a first binary number or a second polarization state that corresponds to a second binary number; and a system control (1108) configured to receive signals from the polarization states and the raw bit generator, the signals corresponding to the polarization states, and output a random number based on the first and second polarization states of the single photon. ® KIPO & WIPO 2009
