They found that co-propagation of a QKD quantum channel at 1310 nm using 60-channel WDM at 100 Gb/s produced a total data rate of 6 Tb/s. In addition, emission of a secure key with very high ...
This work shows that we can have co-propagation of the quantum channel with WDM data channels in the same fiber without changing the engineering rules of the operational WDM links. The high secret key ...
