Quantum Waveguides for Indistinguishable Single Photon Sources (QWISPS)

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.
