Single and entangled photon sources for quantum metrology

This project will develop high brightness, high-efficiency entangled photon sources (based on semiconductor quantum dots (QDs)) andit will exploit high-purity single-photon sources (based on ion implantation in diamond and on single molecules), to demonstrate the quantum advantage achieved when using these sources for specific measurements.

The overall objective of the project is to develop bright entangled photon sources based on different application-oriented platforms and to exploit high-purity single-photon sources to demonstrate the quantum advantage achievable using these sources for specific measurements.

Over the last years, significant progress has been made in the implementation of quantum photonics, and specifically single-photon sources, at NMIs. This progress stems from the substantial advancements that were made in the previous EMRP and EMPIR projects EXL02 SIQUTE and 17FUN06 SIQUST, respectively.
