题目：Integrated Quantum Photonics Based on Epitaxial Quantum Dots
摘要：Semiconductor quantum emitters, especially epitaxial quantum dots (QDs) with large optical oscillator strength, are one of the most promising candidates for exploring fundamental quantum physics in solid-state and building quantum photonic devices on-chip. However, the deterministic creation and eventual scalability of single QD devices greatly suffer from the random nature of the QDs produced in their self-assembled growth. In this talk, I will present the breakthrough of scalable and deterministic light-matter couplings based on single-photon hyperspectral imaging. With deterministically coupled QD-microcavity systems, we’ve observed the long-sought-after dynamic resonance fluorescence in cavity quantum electrodynamics and realized quantum photonic devices with state-of-the-art performances, including bright sources of entangled photon pairs, single-photon sources carrying orbital angular momentum, stimulated emission assisted single-photon sources and on-chip pumped single-photon sources. We finally envision long-distance quantum networks based on telecom band QDs via hybrid integration technology.
