Multiple-Access Quantum-Classical Networks
Mohsen Razavi, Timothy C. Ralph, Ping Koy Lam · AIP conference proceedings · 2011
A multi‐user network that supports both classical and quantum communication is proposed. By relying on optical code‐division multiple access techniques, this system offers simultaneous key exchange between multiple pairs of network users. A lower bound on the secure key generation rate will be derived for decoy‐state quantum key distribution protocols.
