US Air Force Plans Quantum-Resilient Network Expansion

Swiss quantum startup Terra Quantum has secured a significant bid to construct a secure long-distance quantum resilient network in the United States. The project, commissioned by the US Department of the Air Force (DAF), will involve a comprehensive feasibility study that integrates cutting-edge quantum technologies.

Terra Quantum's proposal encompasses the utilization of quantum key distribution (QKD), quantum random number generation (QRNG), and non-quantum post-quantum cryptography (PQC) algorithms to establish a highly secure quantum resilient network. The company has already demonstrated the viability of quantum key distribution over an impressive distance of 1707km on optical fibers, setting the stage for even more ambitious endeavors.

"While the initial focus may be on fiber optic networks for QKD, Terra Quantum's expertise extends beyond this realm. We also incorporate Post-Quantum Cryptography (PQC) that can be seamlessly integrated into diverse communication infrastructures, ensuring comprehensive quantum-resistant security across various networks," explained Florian Neukart, the chief product officer at Terra Quantum, in an interview with eeNews Europe.

Neukart further elaborated, "This initial contract marks the beginning of a phased approach to assess the feasibility of the quantum network for the Air Force and solicit input from key stakeholders. The subsequent phase will involve the actual design and implementation of the network, with expectations set on surpassing our previous world record in terms of network length."

One of the distinguishing features of Terra Quantum's approach is the ability to achieve significant distances for QKD without the need for quantum repeaters. By leveraging an intermediate number of photons and existing telecom infrastructure for signal amplification, the company can cover substantial spans without the requirement of repeaters, contingent on factors such as fiber quality.

Looking ahead, Neukart emphasized the adaptability of Terra Quantum's QKD technology to satellite communication requirements, highlighting its potential for secure key exchange over extended distances without the reliance on quantum repeaters, making it a viable option for satellite-based applications.

The awarded contract underscores the pivotal role of quantum technology in fortifying communication systems against emerging quantum threats, thereby enhancing the efficiency and security of US military operations. Terra Quantum's strategic focus on delivering an ultra-secure, long-range communications network underpinned by post-quantum cryptography, QKD, and QRNG reflects a commitment to providing the highest level of cybersecurity and resilience against potential cyberattacks.
