Coherent generation of single photons using a single silicon-vacancy color-center in a diamond nanophotonic cavity
ORAL
Abstract
Single photons are a key enabling resource for scalable quantum communication networks, quantum simulation, and measurement-based photonic quantum computing. These applications require on-demand generation of single-photons with well defined spatial-temporal profiles. Here, we report on progress towards the realization of a deterministic source of indistinguishable photons using a silicon vacancy color center in diamond coupled to a single-sided nanophotonic diamond cavity. We demonstrate high photon collection efficiency into a single-mode fiber, high single photon purity, and the ability to coherently control the spatio-temporal profile of the emitted photons using pulse-shaping techniques. We discuss the prospect to use long-lived nuclear memories in combination with this source to deterministically generate large photonic cluster states for one-way quantum communication and computing.
