Published purpose

The quality of quantum photonic technologies, ranging from communication to computation to sensing, depends on the generation of high-quality quantum states photonic states: either single or entangled photons. The Project addresses this challenge, developing on-demand sources of indistinguishable single photons and entangled photon pairs, on-chip and at telecommunication wavelengths. These sources require the integration and electronic-gating of self-assembled quantum dots, whose sizes and material composition have been carefully engineered to provide telecom photons, with on-chip nanoscale systems, designed to control and optimize quantum light-matter interactions. Together, this combination will for the first time, provide high-quality quantum photonic states on chip that can leverage the full power of the telecommunication industry, providing a powerful new platform for the development of quantum sensing technologies.
