Abstract
Covesion Ltd and The University of Southampton plan to extend our collaborative feasibility study investigating
the use of periodically-poled lithium niobate crystals in single-photon sources for applications exploiting
quantum entanglement. Laser pulses contain different numbers of photons and in our crystals these photons
can be split into pairs; the laws of physics state that if one of these photons is created then the other must also
exist. Based on this premise, detecting one paired photon signals the presence of the other, providing a
predictable source of single photons that can be used for computation. In this project, we seek to reduce the
manufacturing tolerances required to generate similar photons from different sources and our objective is to
prove our new approach across multiple devices. This is an important step in enabling scalable quantum
applications where many predictable photons with the same attributes are needed in parallel, such as quantum
computing.
