OPTICAL-BASED, SELF-AUTHENTICATING QUANTUM RANDOM NUMBER GENERATORS

摘要

Various embodiments of the present invention are directed optical-based quantum random number generators. In one embodiment of the present invention, an optical-based, self-authenticating quantum random number generator comprises an input state generator (1102, 2102) that generates a optical quantum system in a linear superposition of states, a detector (1112-1115, 2108, 2110) that measures the state of the optical quantum system, a system control (1118, 2114) that evaluates a result obtained from measuring the state of the optical quantum system to determine whether or not to append a number associated with the result to the sequence of random numbers. The quantum random number generator may also include a state controller (1104, 1106, 2104), located between the input generator (1102, 2102) and the detector (1112-1115, 2108, 2110), that is operationally controlled by the system control (1118, 2114) in order to maintain the states of the optical quantum system, based on the results obtained from measuring the states of the optical quantum system.
