    • 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.
    • 本发明的各种实施例涉及可以集成到光电子电路中的自认证量子随机位发生器。 在一个实施例中,量子随机位发生器包括传输层,其包括耦合到分支到第一,第二和第三波导中的波导的电磁辐射源。 辐射源产生处于第一偏振状态的电磁辐射脉冲。 极化旋转器可操作地耦合到第二和第三波导并且将在第二波导中传输的脉冲旋转成第二偏振状态,并将在第三波导中传输的脉冲旋转到第三偏振状态。 系统控制基于在第一波导中发送的脉冲的基于偏振的状态产生比特序列,并且基于第二和第三脉冲的基于极化的基础状态来进行层析成像地验证序列的随机性。
