The project “Single and entangled photon sources for quantum metrology (SEQUME)” is a EU / EMPIR funded collaborative project.

The aim of the SEQUME 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 achieved by using these sources for specific measurements. Making single-photon and entangled-photon sources, with the required performance parameters, more readily available, would be significant for the development of quantum technologies and the advancement of quantum-enhanced measurements.
