摘要:

可扩展的光子量子技术基于多个嵌套干涉仪。为了实现这种架构,需要集成光学结构来确保稳定、可控和可重复的操作。在这里,我们展示了一个关键的证明的原则演示的外部控制的光子量子线路的基础上紫外光写入波导技术。特别是,我们提出的非经典干涉的光子对的马赫-曾德尔干涉仪与X耦合器在集成光路中的热光移相器的干涉仪臂之一。

英文摘要:

Scalable photonic quantum technologies are based on multiple nested interferometers. To realize this architecture, integrated optical structures are needed to ensure stable, controllable, and repeatable operation. Here we show a key proof-of-principle demonstration of an externally-controlled photonic quantum circuit based upon UV-written waveguide technology. In particular, we present non-classical interference of photon pairs in a Mach-Zehnder interferometer constructed with X couplers in an integrated optical circuit with a thermo-optic phase shifter in one of the interferometer arms.
