Cavity QED with spins in diamond: Toward a quantum interface between light and matter

An interface that maps the quantum states between light and matter in a reversible manner is of both fundamental and practical importance.   This quantum interface can enable controlled interactions between distant quantum systems and can also distribute quantum information across a network, thereby serving as a quantum interconnect.   In this talk, I will discuss the development and use of a cavity QED system for the quantum state transfer between spins and photons.  The cavity QED system consists of electron spins in diamond coupling to whispering gallery modes in a silica optical resonator.  Possibilities of a phonon-photon quantum interface exploiting optomechanical coupling in these resonators will also be discussed.

Come meet the speaker over coffee and refreshments from 3:45-4:10 pm in the foyer on floor G above the lecture hall.   All Welcome.  Host: Chuanwei Zhang
