摘要:

在许多量子信息技术中,需要能够分辨光子数的探测器。为了在量子信息处理中有用,这样的检测器应该简单、易于使用,并且可扩展以分辨任何数量的光子,因为应用可能需要很大的便携性,例如在量子密码学中。在这里,我们描述了一个时间复用检测器,它使用一对标准的雪崩光电二极管在盖革模式下工作的建设。理论分析和实验测试使用脉冲光源的弱相干光的检测技术。

英文摘要:

Detectors that can resolve photon number are needed in many quantum information technologies. In order to be useful in quantum information processing, such detectors should be simple, easy to use, and be scalable to resolve any number of photons, as the application may require great portability such as in quantum cryptography. Here we describe the construction of a time-multiplexed detector, which uses a pair of standard avalanche photodiodes operated in Geiger mode. The detection technique is analysed theoretically and tested experimentally using a pulsed source of weak coherent light.
