集成量子光子波导电路是实现未来光子量子技术的一种有前途的方法。在这里，我们提出了一种利用绝缘体上硅材料系统的集成光子量子技术平台，其中量子干涉和光量子态的操纵在比以前的实现小几个数量级的组件中得到了演示。在多模干涉耦合器中提出了双光子量子干涉，并在马赫-曾德干涉仪中演示了纠缠的操纵，为全硅光子量子技术平台开辟了道路。
Integrated quantum photonic waveguide circuits are a promising approach to realizing future photonic quantum technologies. Here, we present an integrated photonic quantum technology platform utilizing the silicon-on-insulator material system, where quantum interference and the manipulation of quantum states of light are demonstrated in components orders of magnitude smaller than previous implementations. Two-photon quantum interference is presented in a multi-mode interference coupler, and the manipulation of entanglement is demonstrated in a Mach-Zehnder interferometer, opening the way to an all-silicon photonic quantum technology platform.
