Frequency-correlated 1550-nm photon pairs for quantum communication
Eric A. Dauler, Marius A. Albotǎ, Steven P. Constantine · 2003
We observed frequency correlation of 1550-nm photon pairs generated via broadband parametric downconversion. Wavelength division multiplexing components are used to separate photon pairs into correlated, narrowband channels for potential use in increased-capacity quantum networks.
