SUMMARY:ESE Seminar: "Harnessing Light-Matter Interaction for Photonic Quantum Technologies"
DESCRIPTION:Photonic quantum technologies have a unique potential for applications such as large-scale quantum networks and quantum-enhanced sensing. Furthermore\, photons provide new paradigms for quantum simulations and a testbed for benchmarking the advantage of quantum simulators over the classical ones. These applications demand novel resources such as efficient single-photon sources\, large clusters of entangled photons\, and nonlinear optical gates. A 1D-atom\, a quantum emitter coupled to a single optical mode with high efficiency\, can deliver these functionalities. \nIn this talk\, I will introduce two realizations of an artificial 1D-atom based on a single quantum dot coupled to either a photonic-crystal waveguide or a tunable Fabry-Perot microcavity. To start\, I will present a single-photon source with record efficiency\, speed\, and coherence. I will then go on to discuss the transmission properties of the 1D-atom and show that we can achieve optical nonlinearities at the single-photon level. I will also show that the interplay between the local electric field and the quantum dot can lead to interesting phenomena such as directional emission and nonreciprocal transport for photons. \nAt the end of my talk\, I will present an overview of my feature research direction and my vision for quantum computing and quantum networking using photons.
