Abstract
Quantum key distribution requires photon-pair sources with high spectral correlation. Meanwhile, by applying wavelength-division multiplexing, quantum information capacity can be increased massively. This work experimentally achieves an efficient, high-quality multichannel photon-pair source that matches the standard International Telecommunication Union frequency grid. Strong, uniform spectral correlation over multiple channels is demonstrated by reconstructing the joint spectral intensity with high-resolution, probe-swept stimulated four-wave mixing.
