Oxford Quantum Circuits (OQC) and QinetiQ have cracked the code on uncovering vulnerabilities in military communications systems using quantum computing.
In recent trials, QinetiQ used QQC’s Toshiko quantum computer via a secure cloud interface to see whether quantum tools could analyze complex communications networks.
The team focused on Mobile Ad-Hoc Networks (MANET), infrastructure-free systems widely used in combat zones and disaster response, where units must stay connected without fixed towers or cables.

By running these networks through the quantum platform, researchers were able to pinpoint “critical nodes” — key connection points that, if disrupted, could fracture entire communication chains.
Building on those results, the companies said quantum computing could eventually help militaries strengthen networks against jamming, cyberattacks, and physical disruption.
The tech could also support logistics planning and real-time decision-making in high-pressure operations.
From Lab to Battlefield
The partnership reflects the UK’s growing role in the global race to turn quantum computing from theory into deployable technology.
Both firms argued that quantum systems are beginning to tackle practical defense challenges, rather than remaining confined to research labs.

As part of that push, OQC is rolling out secure data centers in the UK and overseas, giving government and industry users access to its quantum platforms.
“This project is a tangible example of quantum computing’s power to deliver real operational value,” said Gerald Mullally, chief executive officer of OQC.
“Working with QinetiQ has shown how sovereign quantum technology can be applied today to challenges that directly impact defence capability.”
