Quantum computing company IonQ (NYSE: IONQ) announced on the 17th (local time) that it has added a new product, the 'Clavis XG Multiplex,' to its Quantum Key Distribution (QKD) solution 'Clavis XG' series. This new product is designed to make deploying quantum security more practical and easier in metropolitan fiber optic network environments.

Cost Reduction Through Use of Existing Infrastructure

The most notable feature of the Clavis XG Multiplex is that it allows customers to fully utilize their existing network infrastructure while supporting high-performance, physics-based cryptographic key distribution. In particular, it enhances competitiveness over existing solutions by improving product size, maintenance, configuration, and management features in the context of enterprise network integration.

As a result, operators no longer need to design a separate optical network for quantum security or split and dedicate existing networks. This enables the management of long-term encryption risks in network segments where sensitive data is concentrated at a lower cost. It also provides a practical security alternative while the transition to Post-Quantum Cryptography (PQC) is underway across the enterprise.

Jordan Shapiro, President of Quantum Platforms at IonQ, stated, "Quantum security has evolved beyond specialized network environments into a technology that organizations operating core infrastructure must seriously consider. Clavis XG Multiplex allows various types of data to be transmitted over the same optical fiber, increasing the utilization of existing infrastructure, strengthening security, and reducing QKD operating costs."

Strong Response to 'Harvest Now, Decrypt Later' Attacks

IonQ recently identified the 'Harvest Now, Decrypt Later' attack as one of the biggest concerns in the security industry. This method involves collecting currently encrypted data in advance and decrypting it later using powerful future quantum computers. According to a recent survey, 61% of respondents cited this as the biggest security threat in the quantum computing era.

In particular, data requiring protection for decades—such as financial information, regulated data, and strategic confidential information—often travels through Local Area Networks (LANs) controlled internally by companies, making them highly likely to be primary targets for long-term data collection attacks.

Completing Real-World Operational Security Through PQC Integration

The new product is designed to provide stable operation and enterprise-grade reliability even in actual metropolitan networks and LAN environments. When combined with 'Clarion KX,' IonQ's quantum-safe key exchange software platform, it can build a security architecture that integrates quantum-based cryptographic keys with Post-Quantum Cryptography (PQC) technology. This allows customers to move beyond simple security planning stages and apply quantum security to actual operational environments.

IonQ expects this solution to serve as a platform equipped with the scalability and practicality required in real enterprise environments, contributing to the establishment of a multi-layered defense system for data requiring long-term protection.
