Abstract

I will present the recent demonstration of deterministic photon-atom and photon-photon interactions using a single atom coupled to a chip-based micro-resonator. Based on passive, interference-based nonlinearity which leads to deterministic single-photon Raman passage (DSPR), this scheme swaps the quantum states of a single photon and a single quantum emitter (a 87Rb atom, in our case), with no need for any control fields.
Beyond the ability to route single photons by single photons, this scheme can also function as a quantum memory and a photonic universal quantum gate. It can therefore provide a building block for scalable quantum networks based on completely passive nodes interconnected and activated solely by single photons.
