IonQ Introduces Clavis XG Multiplex, Making Quantum Security Deployable at Scale in Metro Networks

New addition to IonQ's Clavis XG Quantum Key Distribution portfolio enables quantum and classical traffic to coexist on existing metropolitan fiber infrastructure

IonQ (NYSE:IONQ), the world's leading quantum platform company, today announced Clavis XG Multiplex, a new addition to the company's Clavis XG Quantum Key Distribution (QKD) portfolio designed to make quantum security even more practical and deployable across metropolitan fiber networks. Within the space, the Clavis XG product line has a clear advantage in enterprise‑grade network integration, from form factor and maintenance to configuration and management.

Clavis XG Multiplex enables high-performance, physics-based key distribution on a customer's existing network infrastructure without requiring operators to redesign, isolate or dedicate optical networks for quantum security. The result is a lower cost, practical way to reduce long-term cryptographic risk now, on the network segments where sensitive data and exposure risk often concentrate, while broader post-quantum cryptography (PQC) migration continues across the enterprise. This multiplex solution is the latest offering in IonQ's quantum security and PQC portfolio.

"Quantum security is moving beyond specialized network environments, making multiplexing a necessary feature for organizations operating critical infrastructure today," said Jordan Shapiro, IonQ President, Quantum Platform. "Clavis XG Multiplex advances IonQ's quantum security platform by giving customers the flexibility to send multiple types of data across the same fiber, making the existing infrastructure more enterprise grade, secure, and QKD cheaper to operate."

One of the most pressing security needs is the "harvest now, decrypt later" threat, which is the top quantum-related concern of 61% of respondents surveyed in a recent study¹. Data that must remain confidential for decades, including financial, regulated and strategic information, often move across local area networks (LANs) under organizational control. These types of local networks are attractive targets for data harvesting now, to be decrypted in the future.

The new offering builds on IonQ's Clavis XG QKD portfolio, delivering enterprise-grade reliability and stable operation in live metro and LAN fiber environments. Combined with Clarion KX, IonQ's end-to-end, quantum-safe key exchange software platform, Clavis XG Multiplex forms a unified quantum security architecture that brings together quantum-derived keys and post-quantum cryptography to help customers move from planning to production deployment.

IonQ delivers quantum security deployment from a platform designed for real-world operations: practical, scalable, and aligned with how organizations build defense-in-depth protections for data that must remain secure over the long term.
