Abstract:
Achieving optical nonlinear interactions at the
level of single photons has been the subject of
extensive research in the last couple of
decades. I will present the recent demonstration
of deterministic, all-optical photon-photon
interactions using a single atom coupled to a
chip-based micro-resonator. Based on
deterministic single-photon Raman passage
(DSPR), this scheme requires no control fields,
and beyond the ability to route single photons
by single photons, can also function as a
quantum memory and even a universal
quantum gate. It can therefore provide a
building block for scalable quantum networks
based on completely passive photonic devices
interconnected and activated solely by single
photons.
