QKD that shares existing metro fiber (Clavis XG Multiplex)

IonQ — IonQ launched Clavis XG Multiplex, letting quantum-key-distribution traffic run alongside classical data on existing metropolitan fiber — so operators need not redesign, isolate or dedicate optical networks for quantum security. Paired with its Clarion KX key-exchange platform, it targets the "harvest-now, decrypt-later" threat and aims to move customers from QKD pilots to production deployment.
