Technologies based on the laws of quantum mechanics are the next stage of industrial and scientific innovation. With far-reaching applications, from super-fast computers and ultra-secure communication to sensitive sensors for biomedical imaging, they will help to provide solutions to many of today’s global challenges. A fundamental building block of optical quantum technologies are light sources that can emit single photons. However, despite large steps forward, current single-photon sources are still insufficient for real, practical uses.
This project will carry out the fundamental work needed to develop a new quantum standard, assessing and establishing new materials and designs for single-photon sources. It will also develop essential elements of supporting measurement infrastructure, such as amplifiers and detectors. By providing access to better single-photon sources, this project will catalyse future innovation in the field of optical quantum technology, and could contribute towards the realisation of a quantum definition of the luminous intensity SI base unit, the candela.
