明亮的偏振纠缠光子对源是量子信息技术的重要组成部分。一般来说，有必要引入一种结合有源光学元件的谐振器，如电光调制器，以增强偏振纠缠光子的受激发射。通过同步激光脉冲在谐振腔中输出受激纠缠光子，实现时间序列运算在技术上是困难的。在本文中，我们提出了一个方案，以扩大受激发射的偏振纠缠光子对使用谐振腔只有被动光学元件。我们展示了该方案的理论方面，并在双通道配置中对该方案进行了原理验证实验演示。
Bright sources of polarization-entangled photon pairs are essential components for quantum information technologies. In general, it is necessary to introduce a resonator that combines active optical components such as an electric optical modulator to enhance the stimulated emission of polarization-entangled photons. It is technically difficult to perform the time series operation to output the stimulated entangled photons in the resonator by synchronizing laser pulses. In this paper, we propose a scheme to scale up the stimulated emission of polarization-entangled photon pairs using a resonator with only passive optical components. We show the theoretical aspects of the scheme and also perform a proof-of-principle experimental demonstration of the scheme in a double-pass configuration.
