250MBaud Gaussian CV-QKD in coexistence with 8x200G PM-16QAM

This dataset comprises the simulation data of the VPItoolkit™ QKD application example "250MBaud Gaussian CV-QKD in coexistence with 8x200G PM-16QAM". This demonstrates the possibility of coexisting Gaussian CV-QKD and two times four classical channels. The classical channels (32 GBaud) are simulated with 8 samples per symbol. The modulation variance is swept to illustrate how excess noise and secret fraction depend on the modulation variance.
