摘要： Various embodiments of the present invention are directed to self-authenticating, quantum random bit generators that can be ingrated into an optoelectric circuit. In one embodiment, a quantum random bit generator (1100, 1400) comprises a transmission layer that includes an electromagnetic radiation source (1106, 1406, 1412) coupled to a waveguide (1108, 1414) branching into a first (1111), second (1110), and third (1112) waveguides. The radiation source generates pulses of electromagnetic radiation in a first polarization state. Polarization rotators (1114-1117) are operably coupled to the second and third waveguides and rotate pulses transmitted in the second waveguide into a second polarization state and rotate pulses transmitted in the third waveguide into a third polarization state. The system control (1104) generates a sequence of bits based on polarization basis states of the pulses transmitted in the first waveguide, and tomographically authenticates randomness of the sequence based on polarization basis states of the second and third pulses.

摘要： A system (100) can include a transmitter (114) that produces an optical signal (118) having a plurality of carrier frequencies and a receiver (116) separated from the transmitter (114) by free space through which the optical signal (118) propagates. The receiver (116) includes an array (200) of detectors of multiple types, with the types being capable of detecting light respectively having the carrier frequencies. A location of an incident area (220) where the optical signal (118) is incident on the detector array (200) generally depends on a misalignment of the receiver (116) relative to the transmitter (114) , but the detectors in the detector array (200) are arranged so that at least one detector of each of the types detects light from the optical signal (118) regardless of where the incident area (220) is on the detector array (200).
