Our research lies at the frontier of quantum optics, in two relatively unexplored research areas: time-domain quantum optics and bright quantum sources.
Time-domain quantum optics studies the quantum properties of very short pulses of light, with durations close to a single optical cycle. It is then not possible to ascribe a well-defined energy to photons, contrary to the usual paradigm of quasi-monochromatic quantum optics. Instead, it is the time of arrival of photons that is well defined.
Bright quantum optics is a new type of quantum resource, with pulses containing millions or billions of photons rather than the few-photon sources usually explored in quantum laboratories. Instead on focusing on photon counting, we explore the properties of the electromagnetic field itself, and generate entanglement between quadratures (amplitudes and phases) rather than photon numbers (intensities).
Our goal is to bring the advantages of quantum resources to everyday optical tasks (spectroscopy, lidar, interferometry, ...) that require brightness.
