We demonstrate the generation of a 16-GHz microwave signal via optical frequency division of an optical-parametric oscillator by Kerr-soliton comb, which is optically synchronized. The resulting noise levels represent...

Using Bragg-scattering four-wave mixing, we prepare frequency-bin qubits and measure a purity of 0.92 through a lossy channel, suggesting viability for quantum networks using existing telecommunications infrastructure...

We demonstrate the generation of a 4-photon, dual-rail cluster state with a lower-bound fidelity of 0.81 consisting of sequences of dual-color photon pairs. Our approach is extendable to general NxM cluster states. &#...

We demonstrate all-optical on-chip synchronization of opposite polarity Kerr combs in the normal group-velocity dispersion regime. Coherent combining of such combs with different spectral profiles allows us to efficie...

We show continuous tuning into an all-optical dark state by modifying coherent interference between coupled photonic resonators. The quality factor is tuned from 50,000 in the bright state to 1.4 million in the dark s...

We theoretically and experimentally investigate the stability of single and multi-pulse normal group-velocity dispersion Kerr-combs in coupled-resonators. We show implementation of a drop-port is critical for suppress...
