Enhancing atomic quantum memory through collective atomic behaviours

Quantum memories are key components in the development of a quantum network. Among their many uses, these memories will facilitate the synchronization of quantum signals at repeater nodes, which are a crucial technology for extending the long-distance reach of quantum communications. Quantum memories facilitate the transfer of quantum information from electromagnetic signals into matter-based quantum states through careful engineering and control of the light-matter interaction. This project will explore the preservation of true quantum information in an atomic quantum memory, beyond established proof-of-concept demonstrations with attenuated classical signals, by relying on expertise from both the home and host institutions in quantum optics and atomic physics. The project will develop the tools for an experimental demonstration proving the preservation of quantum correlations and entanglement in an Autler-Townes splitting atomic quantum memory. Additionally, the project will include theory work exploring how the atomic medium can be enhanced through many-body and multi-atom effects to improve the storage time and the preservation of quantum information.
