WebJul 17, 2024 · Photonic chip integration would greatly benefit quantum key distribution (QKD) systems for secure communication, in terms of compactness, scalability, and well … 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).
WebSep 22, 2024 · Qudit-based QKDs are developed in high-dimensional Hilbert spaces, and thus are also referred to as high-dimensional (HD) QKDs. Generally, QKDs can be divided into two categories—discrete variable (DV) QKDs and continuous variable (CV) QKDs. We consider qubit-based and qudit-based QKDs as DV-QKDs.
