Deterministic single-photon sources for photonic quantum technology

Photons are excellent carriers of quantum information over long distances and can be reliably processed in advanced photonic integrated circuits. One fundamental challenge has been that they are complex to generate, i.e. single-photon sources tend to be inherently inefficient. Solid-state quantum emitters deterministically coupled to nanophotonic circuits have overcome this challenge, and today highly efficient and coherent photon-emitter interfaces are realized, enabling generation of high-quality single-photon sources, multi-photon entanglement sources or photonic quantum gates. In this webinar we will explain the fundamental operational principle of this novel light-matter interfaces and discuss future application areas within quantum computing and quantum networks.
