Light-matter interaction
We have studied the interaction between quantum dots and single photons to control quantum states and improve quantum interfaces, essential for robust quantum computing.
We have explored the energy exchanges between quantum emitters and light fields, revealing insights into quantum coherence and its impact on quantum system performance. This has enabled us to revisit phenomena such as spontaneous emission.
We extend methods for describing spin-photon interfaces from cavity QED to waveguide QED, focusing on four-level systems with polarization, magnetic fields, and nuclear spins.
We have explored the response of our quantum emitters to low photon numbers , examining how minimal photon interactions can lead to significant changes in system dynamics.
We have investigated the use of metallic structures to control spontaneous emission, aiming to simplify technology for brighter and more versatile single-photon sources suitable for a range of applications.
