Non-classical states of light are instrumental for several purposes:
To send quantum information between different nodes of a quantum network (long-distance quantum comunication).
To perform phase-measurement beyond the sensitivity of classical photon sources (photonic quantum metrology, see this for an updated review).
To do quantum computation tasks based either on measurements (one-way quantum computer) or sampling distributions (boson sampling).
To obtain the states required for such purposes one requires both efficient light-matter interfaces & adequate protocols to shape them. Along the past years we have specialized in the generation of multi-photon Fock states, instrumental for quantum metrology tasks, and which are very hard to obtain with current probabilistic methods.
As you could see below, we have exploited the collective dissipation appearing in waveguide QED and the strong-coupling in cavity QED setups, respectively, to develop efficient protocols to generate them. We highlight now some of our most important contributions below (see Publications for a complete list)
