Quantum imaging (QI) is a rapidly developing field of research with stunning progresses and emerging societal applications. Quantum-enhanced imaging schemes harness the beneficial properties of entangled photon pairs allowing transferring amplitude and phase information from one photon state to the other. The main objective of the internship will consist in using a pair of non-degenerated entangled photons at 2 harmonics from the high harmonic frequency comb to perform a quantum imaging experiment . We will study the possibility of transferring the sensing and resolution benefit from one spectral range to another one. The quantum correlations between the two photons from the same harmonic generation process will be used to transfer amplitude and phase information between the two photons. Ultimately, the candidate will investigate novel protocols to create high-resolution label-free images of complex structures (e.g. cells) embedded inside biological tissues.
