| Description | This project enabled the first targetted UK effort in on-chip waveguide integrated single photon detectors. We carried out proof of principle studies on lithium niobate substrates, using advanced low temperature nano-optical mapping techniques to determine device uniformity. |
| Exploitation Route | As mentioned, this early work enabled more rapid progress on follow up EPSRC projects on GaAs and silicon-on-insulator quantum photonic circuits. There is at least one international start up (Psi Quantum) aiming to commercialize quantum photonic circuits, most probably using silicon. Interestingly, a German/US consortium (Paderborn/NIST) are now revisiting the lithium niobate quantum photonic approach. |

| Description | There are now several international start ups aiming to commericalize quantum photonic circuits e.g Psi Quantum USA and Sparrow Quantum Denmark. Our early work in this field has had a role in stimulating this commerical exploitation. |
