Xairos Achieves Two-Kilometer Milestone with Ares Quantum Optical Terminal

Summarize this article with:
Free-Space Milestone Achieved: Xairos establishes simultaneous quantum and optical links over a two-kilometer range using a single terminal.Terminal Capabilities Validated: Ares Quantum Optical Terminal integrates 10 Gbps free-space optical communications with entangled photon distribution and Quantum Time Transfer (QTT).Contested-Environment Readiness: Advances quantum-secure communications and resilient PNT for real-world deployment in RF- and GPS-denied settings.Xairos Systems announced the completion of two-kilometer free-space range testing for its Ares Quantum Optical Terminal, successfully establishing simultaneous quantum and optical links with Space Development Agency-compliant optical communications. The demonstration validates quantum-secure, high-data-rate communications and resilient position, navigation, and timing (PNT) capabilities in RF- and GPS-denied environments.The fully integrated Ares Quantum Optical Terminal combines 10 Gbps free-space optical communications, entangled photon distribution for timing synchronization and encryption key sharing, and a stable clock ensemble disciplined by Xairos’ exclusive Quantum Time Transfer (QTT) technology, all housed within a ruggedized compact package. This free-space testing—distinct from fiber-based demonstrations—confirms operational performance of the combined capabilities in a single terminal and represents a critical validation step toward real-world deployment.The system underpins a communications and PNT mesh network for aircraft, uncrewed aerial systems (UAS), ships, and other assets operating in contested environments. It also serves as the foundation for a future space-based architecture spanning satellites, air vehicles, and ground nodes.The achievement aligns with growing defense and government demand for resilient alternatives to traditional GNSS-based timing and RF communications, enabling secure operations where GPS and RF signals are jammed or unavailable. By delivering sub-nanosecond precision timing via quantum entanglement alongside high-bandwidth optical links, the Ares Quantum Optical Terminal supports multi-domain operations and critical national infrastructure protection.Xairos continues to advance the platform through targeted development initiatives, including collaboration with the Colorado Quantum Incubator on the Quantum Timing Center, positioning the company to meet emerging requirements for quantum-enhanced synchronization in both commercial and defense markets.Find out more here.Further articles, reports, and the latest quantum computing news may be found at The Qubit Report.Sumitomo Mitsui Banking Corporation and Toshiba Corporation have jointly developed the SMBC/TOSHIBA Quantum Driven Diversified Equity Indices using Toshiba’s Simulated Bifurcation Machine.
