"due to dispersion-designed structural geometry, interacting lights group-velocity mismatch 100% smoothed... qubit information transferred between different wavelengths without losing coherence, entanglement... nonlinear optical X-cut thin film lithium niobate... broadband 2nd-harmonic up to 13 nm usings mode hybridization allowing precise control in micro-racetrack resonator... enhanced quantum light sources, larger capacity multiplexing, more effective multichannel optical information processing"
