Abstract

The efficient coupling of a quantum emitter to a propagating mode is eagerly sought after since it would enable a number of new opportunities in quantum optics and quantum-information processing. Such a setting would not only constitute a near-ideal deterministic single-photon source, but also enable giant nonlinearities that are sensitive at the level of just a few photons. Quantum-dot sources have in recent years matured significantly and are now capable of producing highly indistinguishable and high-purity single photons. Combined with the ability to enhance light-matter interaction with photonic nanostructures this opens for a realm of novel opportunities for all-solid-state integrated quantum-information processing [1].
