Quantum Fabrix Secures £6.8M to Deploy Atomic Clocks in Orbit and Data Centers

As satellite constellations and terrestrial data centers increasingly rely on precise timing infrastructure, the vulnerability of traditional GPS signals to jamming and space weather has become a critical bottleneck. To address this, Oxford University spinout Quantum Fabrix (QFX) has secured a £6.8 million contract from Innovate UK to advance its SrROCK program. The funding will finance the engineering of a compact, low-power strontium optical clock designed specifically for space-relevant testing and future satellite missions.

Unlike legacy atomic clocks that are bulky and confined to laboratory environments, QFX is building modular quantum hardware that can operate from room temperature down to cryogenic levels. Phase II of the SrROCK initiative focuses on turning these precision atomic and vacuum technologies into manufacturable, field-ready devices. By miniaturizing the physics package, the startup aims to provide a resilient timing alternative that does not depend on external satellite signals, ensuring continuous operation for critical national infrastructure.

The contract marks a significant transition for the UK quantum sector from theoretical research to commercial deployment. Led by former Infleqtion executives Dr. Timothy Ballance and Sadie Mansell, QFX is actively engaging with spacecraft manufacturers and data center operators to define deployment requirements. If successful, the space-tested atomic clocks could fundamentally shift how orbital networks synchronize, reducing reliance on vulnerable legacy navigation systems while establishing a sovereign supply chain for advanced timing hardware.
