Patent number: 7849122Abstract: Various embodiments of the present invention are directed to self-authenticating, quantum random bit generators that can be integrated into an optoelectronic circuit. In one embodiment, a quantum random bit generator comprises a transmission layer that includes an electromagnetic radiation source coupled to a waveguide branching into a first, second, and third waveguides. The radiation source generates pulses of electromagnetic radiation in a first polarization state. Polarization rotators 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 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.Type: GrantFiled: April 18, 2007Date of Patent: December 7, 2010Assignee: Hewlett-Packard Developmemt Company, L.P.Inventors: Marco Fiorentino, Raymond G.
