Quantum Light Sources Compatible with Solid State Quantum Memories
Advanced quantum experiments involving entanglement between remote material systems require the storage of non-classical light in quantum memories, in particular photons part of an entangled state.
The creation of quantum light compatible with quantum memories is a challenging task because the created photons must have a strong interaction with the atomic system used as quantum memory. In order to maximize the interaction, the photons must thus have a very precise frequency corresponding to the optical transition of the atoms used and must have a spectral bandwidth smaller than the bandwidth of the quantum memory. In this project, we investigate ways to implement quantum light sources compatible with solid-state quantum memories, e.g. based on cavity enhanced spontaneous down-conversion.
