Caption

(a) The physical structure of the quantum network. The spectrum is split into 30 ITU grid channels via a 100 GHz-DWDM. CH17 to CH31 are numbered from 1 to 15 respectively, and the numbers with opposite sign denote corresponding to channels CH33-CH47. The architecture of wavelength allocation is omitted in the small trapezoid multiplex blocks. Each small block with colored digital symbols constructs a wavelength group distributed by the network processor. (b) Each pair of signal photon and idler photon is indicated by the same colored bars with and without opposite digital sign. (c) Illustration of SFG progress. Photons generated in pairs by spontaneous parametric down-conversion process are multiplexed into the SFG experiment to realize encoding and quantum communication.
