The route towards quantum computing is challenging as it requires small scale implementation and high efficiency. The Nanogain project is an attempt to fulfill this task. Officially started in 2012, the Nanogain project aims to create a photonic-integrated circuit working at room temperature, designed for single photon handling and detection. It combines together 3 different components (see Fig. 1):

To achieve this goal we need a reliable single photon source, a high efficiency coupling between all the optical devices and a very sensible photodetector with low reset time. To know more, go to our publication list.

The purpose is to create an on-chip photonic circuit which include a single photon emitter (nanoparticule), an optical circuit (waveguide) and a single photon detector.
