Oxford University spinout Quantum Fabrix Ltd (QFX) has been awarded a £6.8 million contract from Innovate UK to develop compact atomic and vacuum hardware for high-precision timing. The project, SrROCK Phase II, targets low-power strontium optical-clock packages intended for data center synchronization and future satellite missions.
Project SrROCK: Advancing Precision Timing
SrROCK Phase II aims to miniaturize a strontium optical clock into a rugged, energy-efficient package suitable for operational deployments. The system combines an atomic strontium source with a sealed ultra-high-vacuum enclosure and integrated optical control to deliver timing stability far beyond conventional crystal oscillators. That level of precision matters for distributed systems that require sub-nanosecond synchronization.
Strategic Impact for UK Quantum and QFX’s Vision
The Innovate UK award strengthens UK capability in foundational quantum hardware, supports domestic manufacturing, and helps protect intellectual property in a rapidly growing market. The project will create skilled roles in engineering and manufacturing while positioning QFX to compete in timing and navigation applications across terrestrial and space sectors.
Dr. Timothy Ballance, CEO of QFX, said, “This funding allows us to prove core technologies under operational constraints and gain access to the timing market that underpins distributed quantum systems and satellite services.”
QFX’s Quantum Hardware Foundation
QFX is building the hardware layer needed for fault-tolerant distributed quantum computing. Their modular approach pairs compact atomic sources, robust vacuum systems, and optical quantum interfaces to form field-deployable nodes. Precise timing is a foundational element for quantum networking, entanglement distribution, and synchronized control across geographically separated quantum processors.
SrROCK Phase II is more than a clock project. It is a step toward practical, scalable infrastructure that will support future quantum networks, resilient data center operations, and satellite services that depend on deterministic, high-accuracy time.
