Quantum Waveguides for Indistinguishable Single Photon Sources (QWISPS)

Covesion Ltd和南安普顿大学计划合作进行一项可行性研究，以调查在利用量子纠缠的应用中，周期性极化的铌酸锂晶体在单光子源中的应用。我们的晶体可以将单个光子的能量分裂并守恒为两个不同颜色的较低能量的光子；根据物理定律，如果这些光子中的一个被创造出来，那么另一个必然也存在。在这个项目中，我们试图降低在平行源之间产生难以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。这是实现可伸缩量子应用的重要一步，在这些应用中，需要并行处理许多不可区分的光子，例如量子计算。

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.
