Abstract: I will present our demonstration of a control-fields-free, deterministic interface between a single photon and a single atom [1,2]. Relying on Single Photon Raman Interaction (SPRINT) [2-4], this completely-passive scheme swaps a flying qubit (encoded in the two possible input modes of a photon), with a stationary qubit (encoded in the two ground states of the atom), and can be also harnessed to perform universal quantum gates.
Using SPRINT we experimentally demonstrated all-optical switching of single photons by single photons , and deterministic extraction of a single photon from an optical pulse . Applicable to any atom-like Lambda system, SPRINT provides a versatile building block for scalable quantum networks based on completely passive nodes interconnected and activated solely by single photons.
