Quantum Waveguides for Indistinguishable Single Photon Sources (QWISPS)

Covesion有限公司和南安普顿大学计划进行一项合作可行性研究，以研究在单光子源中使用周期性极性铌酸锂晶体用于开发量子纠缠的应用。我们的晶体可以将单个光子的能量分裂并保存为两个不同颜色的低能量光子；物理定律表明，如果其中一个光子被创造出来，那么另一个光子也必须存在。在这个项目中，我们试图减少在平行光源之间产生无法区分的光子所需的制造公差，我们的目标是在多个设备上证明我们的新方法。这是实现可扩展量子应用的重要一步，在这些应用中，并行需要许多无法区分的光子，比如量子计算。

Covesion Ltd and The University of Southampton plan a collaborative feasibility study to investigate the use of periodicallypoledlithium niobate crystals in single-photon sources for applications exploiting quantum entanglement. Our crystalsenable the energy of a single photon to be split and conserved as two lower-energy photons at different colours; the laws ofphysics state that if one of these photons is created then the other must also exist. In this project, we seek to reduce themanufacturing tolerances required to generate indistinguisable photons between parallel sources and our objective is toprove our new approach across multiple devices. This is an important step in enabling scalable quantum applicationswhere many indistinguishable photons are needed in parallel, such as quantum computing.
