The student will work on semiconductor quantum light sources. Light is an ideal carrier of quantum information as photons are fast, cheap and easy to encode with quantum-bits carried in their polarisation, phase, time or path degrees of freedom. This project will work with a light source based on a single Indium-Gallium-Arsenide semiconductor quantum dot, as these can offer > 99% spectrally pure photons at high efficiency.The project is funded by the UK National Hub in Quantum Computing and Simulation (Hub-QCS). The source will be produced in Cardiff's Institute for Compound Semiconductors cleanroom and tested in our new optical labs. The focus of year 1 will be increasing the efficiency and purity of the source through design and experiment. In Year 2 the student will collaborate with partners in the Hub-QCS to demonstrate re-routing of photons in prototype network. In Year 3 the student will build on previous research to demonstrate non-linear optical effects in the device.

学生将从事半导体量子光源的研究。光是量子信息的理想载体，因为光子是快速，廉价和容易编码的，量子比特携带在它们的偏振，相位，时间或路径自由度。该项目将使用基于单个铟镓砷半导体量子点的光源，因为这些量子点可以以高效率提供> 99%的光谱纯光子。该项目由英国国家量子计算和模拟中心（Hub-QCS）资助。该光源将在卡迪夫的化合物半导体研究所洁净室生产，并在我们新的光学实验室进行测试。第一年的重点将是通过设计和实验提高源的效率和纯度。在第二年，学生将与Hub-QCS中的合作伙伴合作，演示光子在原型网络中的重新路由。在第3年，学生将建立在以前的研究，以证明在设备中的非线性光学效应。
