Quantum optics with strongly interacting Rydberg atoms

报告摘要：Manipulation of light at the single quanta level is an essential goal in quantum optics, due to its importance for quantum networks, quantum computing and testing of fundamental quantum mechanics. However, performing such quantum operations on photons in an efficient way turns out to be extremely hard, as photons usually don’t interact with each other. Ensembles of high-lying Rydberg atoms feature strong, controllable and long-range interactions and excellent matter-light quantum interface, opening the door to deterministic photonic quantum operations. In this talk, I will present our recent results in using Rydberg atomic ensembles for the generation of non-classical photonic states. We demonstrate the on-demand generation of Rydberg single photons with near-unity purity and indistinguishability and high fidelity linear optical quantum logic gate using these photons.
