Cost-Efficient Quantum Key Distribution (QKD) Over WDM Networks

Quantum key distribution (QKD) uses the laws of quantum mechanics to distribute secret keys with information-theoretic security. To realize QKD for secure communications among multiple distant users, fiber-based QKD networks can be deployed with today ’ s available technologies. Incorporating ...
