The Exotic Quantum Matter (EQM) Group is looking for a highly motivated Master 2 student to characterize a single-photon detection system that will subsequently be integrated into the experimental platform. The EQM group operates a quantum simulator based on ultracold potassium atoms to study strongly interacting quantum matter and light–matter interactions. The EQM team has already demonstrated strong photon–photon interactions through classical measurements of optical intensity and phase. The next step is to investigate these interactions at the level of individual photons, where quantum correlations become directly accessible. The internship will establish a two-channel single-photon detection system based on two single-photon avalanche diodes (SPADs) and a high-resolution photon arrival-time tagger. The system will be used to measure the second-order photon correlation function g²(τ).
