Dirk Englund: Quantum Optics on Photonic Integrated Chips

Dirk Englund, Columbia University

Abstract

Photonic integrated chips provide a way to control the interaction of photons with single emitters in solids, such as semiconductor quantum dots or color centers. I will describe how this controlled light matter interaction can be used to construct basic components for quantum information science. I will discuss recent work on cavity-enhanced generation of single photons; nonlinear optical interactions at the single photon level; nonclassical state generation by photon blockade and tunneling; and some early directions on cavity-enhanced optical interactions with long-lived spin qubits in diamond.
