Missions

The candidate will participate in the development of quantum light state sources for optical quantum computing in the framework of the European FET OPEN PHOQUSING project. The objective is to explore new types of encoding: encoding in frequency and in the basis of number states.

In order to obtain frequency encoded photonic qubits, the candidate will perform quasi-resonant excitation experiments on single quantum dot in optical cavities components. The objective will be first to demonstrate the creation of frequency and polarization hyper-encoded single-photon states. In a second step, we shall explore protocols to manipulate quantum information taking advantage of this new encoding. Another experimental protocol will be implemented for the generation of pure states in quantum superposition of 0 and 1 photon. The objective will be to demonstrate the generation of arbitrary qubits in this basis and to increase the generation rate i.e. the brightness of the sources of these original and promising states for quantum information.

Activities

In practice, the candidate will conduct laboratory experiments with 4K sources, superconducting detectors, photon arrival time correlation devices: set-up, automation, measurements, adjustments. s.he will also conduct simulations and write scientific papers, present his results in conferences etc. S.He will participate in the supervision of trainees and PhD students of the teams and in the collaborations in the framework of the PHOQUSING project and the national quantum plan (PEPR NISQ2LSQ).
