Quantum key distribution and 1 Gbps data encryption over a single fibre
Quantum key distribution and 1 Gbps data encryption over a single fibre
We perform quantum key distribution (QKD) over a single fibre in the presence of four classical channels in a C-band dense wavelength division multiplexing (DWDM) configuration using a commercial QKD system. The classical channels are used for key distillation and 1 Gbps encrypted communication, rendering the entire system independent of …
