Abstract

For quantum information technologies to become mainstream, they must be integrated into microchips. The authors present all-optical generation of nonclassical squeezed light (i.e. with quantum noise reduced below the shot-noise level) using an ultracompact broadband cavity in CMOS-compatible silicon nitride. Such a source of bright squeezed light, operating at technologically accessible power levels, paves the way for quantum enhanced sensing, quantum interconnects, and quantum information processing via a scalable, on-chip platform.
