Scientific project:
– we will study the quantum properties of the state emitted by electrically injected devices and we will add novel on-chip functionalities for the state manipulation, like electro-optics-based phase shifters.
– in collaboration with the theoreticians of our group, we will exploit the assets of the states emitted by our devices (wide spectral band, frequency anti-correlations, cavity effects) for fundamental studies in quantum metrology [4] and quantum computing [5].
– in collaboration with the team Quantum Information (LIP6) we will work on the deployment of the national quantum communication testbed and we will test the performances of our devices in real-world metropolitan quantum networks.
This project will combine device design and fabrication, quantum optics measurements, and theory and applications to QI protocols. It will benefit from the collaboration with the Center of Nanosciences and Nanotechnologies and will take place in the framework of the national Quantum Communication Testbed Project and of the European Quantum Secure Networks Partnership.
