Quantum optics at the nanoscale
We investigate the generation and manipulation of quantum states of light in hybrid systems made of optical nanostructures and quantum emitters. We are interested in the interplay between the quantum nature of light, the dramatic enhancement of electromagnetic fields and the strong modification of quantum light sourcesin proximity of metal surfaces. We have so far demonstrated the complex behaviour of coherent coupling between a nanostructure and a two-level system and that squeezed light from a single emitter can be boosted several order of magnitudes in terms of amplitude and bandwidth. A future goal is to establish a connection between such hybrid systems and quantum entanglement in order to achieve a more rational design of states of light for quantum interferometry.
