Systems and methods for single chip quantum random number generation

摘要

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.
