… Pioneering work on QKD in WDM environment has been performed with DV-QKD
systems, in coarse-WDM [1] as well as later in dense-WDM configurations [2, 3], however
over distances below 25 km. Several DV-QKD experiments have then tried to extend the
distance for mixed QKD/WDM. In [4], 4 classical channels where multiplexed with a DV-QKD
system and 50 km operation was demonstrated. However, the input power of the classical
channels was attenuated to the smallest possible power compatible with the sensitivity limit …

We give a survey of some of the recent progress made in deploying quantum and classical communications over a shared fiber, focusing in particular on results obtained using continuous-variable QKD.
