Keys are generated using quantum light properties. Any eavesdropping attempt changes the quantum state, immediately revealing intrusion.
NIST-certified post-quantum cryptography algorithms run alongside QKD to protect against future quantum computers.
QKD signals operate on separate wavelengths, sharing the same fiber with regular network traffic without requiring new cables.
