Abstract
Systems, apparatuses, methods, and computer program products are disclosed for quantum random number generation (QRNG). An example method includes generating, by encoding circuitry of a QRNG chip, a set of time-bin qubits based on a first optical path length. The example method further includes transmitting, by the encoding circuitry of the QRNG chip, the set of time-bin qubits over an optical line. The example method further includes receiving, by decoding circuitry of the QRNG chip, the set of time-bin qubits over the optical line. The example method further includes measuring, by the decoding circuitry of the QRNG chip and based on a second optical path length different from the first optical path length, the set of time-bin qubits to generate a decoded set of bits. In some embodiments, the example method further includes generating, by session authentication circuitry, a session key based on the decoded set of bits.
