Seminarium KMMF "Teoria Dwoistości"

Mapping quantum information from light to matter (such as atoms) is a challenging task if we wish for high efficiency and low noise, that enable operation in the so-called quantum regime - at the level of single photons or excitations. This crucial task can allow us to combine the properties of photons (which are best for long-distance transmission) and matter (which is best to facilitate interactions), in order to both process and transmit quantum information. I would like to present my efforts at constructing such light-matter interfaces, toward the goal of constructing a quantum network, with many side quests and other applications arising along the path. I will give a general introduction to the principles of operation of such interfaces, followed by examples of experimental implementations. I will also present our favorite experimental and theoretical tools enabling us to design new quantum protocols.
