Summary:

Jean-Baptiste Béguin's research at QUANTOP centers on optical nanofibre-trapped atom interfaces for quantum memories and quantum networks. Research: (1) nanofibre-trapped cold Cs atoms — quantum noise spectroscopy of atom-light spin coupling; (2) single-photon storage and retrieval from nanofibre-guided modes; (3) sub-Poissonian atom loading. Key direction in CBQS center for quantum sensing via coherent atom-photon interfaces.
