US Patent 11483144 Systems and methods for time-bin quantum session authorization

Systems, apparatuses, methods, and computer program products are disclosed for session authentication. An example method includes determining, by decoding circuitry, a set of optical path lengths to use for measurement. The example method further includes receiving, by the decoding circuitry, a set of time-bin qubits. The example method further measuring, by the decoding circuitry and based on the determined set of optical path lengths, the set of time-bin qubits to generate a set of bits. The example method further includes generating, by session authentication circuitry, a session key based on the generated set of bits.
