    • Systems, apparatus, and methods using an integrated photonic chip capable of operating at rates higher than a Gigahertz for quantum key distribution are disclosed. The system includes two identical transmitter chips and one receiver chip. The transmitter chips encode photonic qubits by modulating phase-randomized attenuated laser light within two early or late time-bins. Each transmitter chip can produce a single-photon pulse either in one of the two time-bins or as a superposition of the two time-bins with or without any phase difference. The pulse modulation is achieved using ring resonators, and the phase difference between the two time-bins is obtained using thermo-optic phase shifters and/or time delay elements. The receiver chip employs either homodyne detection or heterodyne detection to perform Bell measurements.
    • 公开了使用能够以高于千兆赫兹的速率运行的集成光子芯片进行量子密钥分配的系统,装置和方法。 该系统包括两个相同的发射机芯片和一个接收器芯片。 发射机芯片通过在两个早期或晚期时间段内调制相位随机衰减的激光来编码光子量子位。 每个发射器芯片可以在两个时间盘中的一个中产生单光子脉冲,或者作为具有或不具有任何相位差的两个时间槽的叠加。 使用环形谐振器实现脉冲调制,并且使用热光学移相器和/或时间延迟元件获得两个时间间隔之间的相位差。 接收机芯片采用零差检测或外差检测来执行贝尔测量。
