SUMMARY:ESE Seminar: "Quantum Nanophotonics: Engineering Atom-Photon Interactions on a Chip"
DESCRIPTION:Abstract: The ability to engineer controllable atom-photon interactions is at the heart of quantum optics and quantum information processing. In this talk\, I will introduce a nanophotonic platform for engineering strong atom-photon interactions on a semiconductor chip. I will first discuss an experimental demonstration of a spin-photon quantum transistor [1]\, a fundamental building block for quantum repeaters and quantum networks. The device allows a single spin trapped inside a semiconductor quantum dot to switch a single photon\, and vice versa\, a single photon to flip the spin. I will discuss how the spin-photon quantum transistor realizes optical nonlinearity at the fundamental single quantum level\, where a single photon could switch the transmission of multiple subsequent photons [2]. I will next discuss the promise of realizing photon-mediated many-body interactions in an alternative solid-state platform based on a more homogeneous quantum emitter\, silicon-vacancy (SiV) color centers in diamond. I will introduce our efforts in creating strong light-matter interactions through photonic crystal cavities fabricated in diamond [3]\, and the use of cavity-stimulated Raman emission to overcome the remaining frequency inhomogeneity of the emitters [4]. Finally\, I will outline the exciting prospects of applying inverse designed nanophotonic structures into quantum optics\, and their potential applications in engineering photon-mediated atom-atom interactions.\nReferences\n[1] S.
