IonQ Launches Clavis XG Multiplex to Scale Quantum Security in Metro Networks

Event summary

  • IonQ introduced Clavis XG Multiplex, a new quantum key distribution (QKD) solution for metropolitan fiber networks.
  • The product enables multiplexing of multiple data types over existing fiber infrastructure without network redesign.
  • Clavis XG Multiplex addresses the 'harvest now, decrypt later' threat, a top concern for 61% of respondents in a 2026 Thales Data Threat Report.
  • The solution integrates with IonQ’s Clarion KX software for end-to-end quantum-safe key exchange.

The big picture

IonQ’s Clavis XG Multiplex addresses a critical gap in quantum security by enabling scalable deployment over existing fiber networks. This move aligns with the broader industry shift toward defending against 'harvest now, decrypt later' threats, particularly in sectors handling long-term sensitive data. The solution’s ability to operate alongside post-quantum cryptography migration positions IonQ as a key player in the evolving quantum security landscape.
