| Abstract Scope |
High-quality factor microresonators (Q > 2 million) made of low-loss deposited materials such as silicon nitride are a fertile ground for scalable generation of quantum states by harnessing the spectral degree of freedom of photons. We experimentally demonstrate how nonclassical states such as highly squeezed light can be generated with modest optical powers and broad bandwidths on small form-factor foundry-compatible chips, due to the strong spatial and spectral confinement offered by nanophotonics. Silicon nitride’s large third-order material nonlinearity plays a significant role in the nontrivial dynamics of quantum light generation, as revealed by our theory and numerical simulations. These squeezed states have noise below the standard quantum limit dictated by Heisenberg’s uncertainty relation, and exhibit entanglement in the frequency domain, making them promising for field-deployable quantum-enhanced sensing and for continuous-variable quantum information processing. |
