Abstract: Quantum information science (QIS) technologies for computing, communications, sensing, and metrology rely on the ability to generate and detect non-classical information using light and matter. Photonics plays a central role in QIS because of the inherent scalability and low-loss, high-speed transmission of light. Yet, despite its ubiquitous presence, there are no high-performance, scalable, turnkey sources of quantum light, such as single photons or entangled-photon pairs.

The invention of optical-frequency combs has transformed the fields of precision metrology, spectroscopy, and electronic/photonic signal generation. Now, a new and incredibly promising platform for frequency combs has emerged—one in which phase coherent combs are generated in nanofabricated ring resonators using quantum nonlinear photonics.
