High-speed integrated qkd system

WebBased on these results, the dead time of the SNSPD we use in our QKD system is about 3.4 ns for the 1/e-delay time, and we set the time separation between e and l to be 12 ns. This short time separation not only allows high-speed detection but also greatly simplifies frequency stabilization of the light source (LS).
