We demonstrate fast polarization and path control of photons at 1550 nm in lithium niobate waveguide devices using the electro-optic effect. We show heralded single photon state engineering, quantum interference, fast state preparation of two entangled photons, and feedback control of quantum interference. These results point the way to a single platform that will enable the integration of nonlinear single photon sources and fast reconfigurable circuits for future photonic quantum information science and technology.
我们在铌酸锂波导器件中利用电光效应演示了在 1550nm 处的光子的快速偏振和路径控制。我们展示了单光子态工程、量子干涉、两个纠缠光子的快速态制备以及量子干涉的反馈控制。这些结果为实现一个单一平台指明了方向，该平台将能够集成非线性单光子源和快速可重构电路，用于未来的光子量子信息科学和技术。
