Technologies that use individual photons to process information have the potential to revolutionise computation by harnessing the power of quantum mechanics. The single photons required can be generated in pairs using frequency conversion techniques driven by high-power pulsed lasers. This project will aim to develop single photon sources utilising the unique capabilities of bespoke optical fibre that you will fabricate. Known as photonic crystal fibre, it guides light within a matrix of air holes that run along the length of the fibre, and the properties of the fibre can be engineered by controlling its structure. Combined with active switching, this fibre enables the production of very high-quality single photons for use in next-generation quantum technologies. The aim of this PhD project is to develop high-performance single-photon sources based on four-wave mixing (FWM) in bespoke optical fibre. The studentship will have three specific goals: 1. Incorporate advanced microstructured fibre into existing actively-switched photonic routers to increase count rates and reduce noise in multiplexed single-photon sources;2. Develop narrowband FWM sources in microstructured fibre;3. Design and build highly nondegenerate FWM sources with the potential to act as entanglement swapping telecoms-wavelength photonic interconnects between communication nodes.

使用单个光子处理信息的技术有可能通过利用量子力学的力量来彻底改变计算。所需的单光子可以使用由高功率脉冲激光器驱动的频率转换技术成对产生。该项目的目标是利用您将制造的定制光纤的独特功能来开发单光子源。它被称为光子晶体光纤，它在沿着光纤长度延伸的气孔矩阵内引导光，并且可以通过控制其结构来设计光纤的特性。与主动开关相结合，这种光纤能够产生非常高质量的单光子，用于下一代量子技术。该博士项目的目标是开发基于定制光纤中的四波混频（FWM）的高性能单光子源。该奖学金将有三个具体目标： 1. 将先进的微结构光纤纳入现有的主动开关光子路由器中，以提高计数率并降低多路复用单光子源中的噪声；2.开发微结构光纤窄带FWM源；3．设计和构建高度非简并 FWM 源，有可能充当通信节点之间的纠缠交换电信波长光子互连。
