Abstract
An on-demand distribution of pairs of polarization-entangled frequency-correlated photons is provided. The pairs are frequency-correlated in different bands of a multiband spectrum which may include the C-Band and the L-Band. The pairs are provided to wavelength selective-switches (WSS), which may be simultaneously controlled to provide the pairs to different receivers that are respectively connected to the output ports of the WSSes. Each WSS has a plurality of frequency channels of δf-width bins aligned to the ITU grid. A network controller receives a request for the distribution of one or more pairs to a pair of receivers and controls frequency-correlated channels in the WSSes to provide the pair(s) to the receivers.
