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 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...
