随着量子计算和量子技术领域的迅速发展，人们对集成电路中光子和光子态的产生、检测和逻辑处理的要求越来越高。量子技术需要大量的片上光子源和光子探测器，在数十万到数百万之间，以进行高层次的计算和大规模的逻辑拓扑。因此，需要改进集成量子光子学的小型化、可扩展性和性能。特别是，能够产生高保真度的纠缠和相干光子的光子源是有效实现此类量子计算技术的必要条件。集成光子学向大规模晶圆方向的发展，将使量子逻辑电路的未来应用达到与现代世界中流行的更传统的基于电子的计算技术相似的水平。

With the rapidly developing field of quantum computation and technologies, there is a growing requirement for generation, detection and logical manipulation of photons and photonic states to be incorporated with integrated circuits (ICs). Quantum technologies require high numbers of on-chip photon sources and photon detectors, in the order of hundreds of thousands to millions, to carry out high level computation and large-scale logic topologies. There is therefore a demand for improvement on the miniaturisation, scalability and performance of integrated quantum photonics. In particular, photon sources that are able to generate entangled and coherent photons with high fidelity are imperative to effective implementation of such quantum computational technologies. Development of integrated photonics towards large scale wafers would allow future applications in manufacture of quantum logic circuits on a level similar to that seen in the more traditional electronics-based computation technologies that are prevalent in the modern world.
