ICE-Quantum - A Modular Cryogenic Architecture for Scalable Quantum Technologies

ICE-Q delivers high-performance cooling, adaptable system design, and enhanced connectivity for evolving quantum applications.

At ICEoxford, we are redefining how cryogenic infrastructure supports the next generation of quantum technologies. Building on decades of experience, we have developed the ICE-Q platform, a modular, scalable system architecture designed to overcome the limitations of traditional large-scale cryostats. 

Conventional systems rely on cylindrical designs that become increasingly difficult to scale and maintain as quantum hardware grows in complexity. With ICE-Q, we have reimagined this approach, introducing a series of compact, cube-shaped modules that integrate seamlessly into a standard 19-inch rack, enabling deployment.

As Greg Graf, our Engineering Manager, explains: “We wanted to create a robust, modular and scalable solution that enables different quantum technologies to be integrated into the cryostat. This approach offers much more flexibility, allowing different modules to be used for different applications, while still delivering the efficiency and reliability needed for operational use.” 

At the core of ICE-Q is a modular architecture built for adaptability. The standard configuration combines a cryogenic module delivering cooling power, a payload module for housing quantum devices or experiments, and a side-loading I/O module that provides high-density connectivity to the external environment. This architecture supports thousands of connections within a compact footprint, while maintaining the flexibility to scale for more demanding applications. 

The cube-based design also transforms how systems are accessed and maintained. Removable panels and mechanically bonded assemblies allow modules to be integrated, reconfigured, or replaced with ease, supporting a more serviceable and resilient system architecture. 

“For quantum computers running in an operational environment, it is really important to minimise the downtime,” notes Emma Yeatman, our Senior Design Engineer. “With this design, we can remove one module for servicing and replace it with another, keeping the system running for longer.” 

Performance and efficiency have been engineered into every layer of the platform. From high-density connectors and integrated cable pre-cooling to advanced heat exchangers produced using additive manufacturing, ICE-Q is designed to manage increasing system complexity without compromising thermal performance. 

As Paul Kelly, our CTO, highlights, “We designed the heat exchangers to exploit the returning cold gas much more efficiently. This allows us to pre-cool the warm gas and reduce the energy required for liquefaction.” 

Alongside the hardware, ICE-Q incorporates an intuitive software layer for monitoring and controlling the ultracold environment. This provides a streamlined, out-of-the-box experience while maintaining the flexibility required for advanced research applications. 

The platform has been shaped through collaboration with industry and research partners, supporting applications ranging from photonics-based quantum systems to cutting-edge fundamental physics research. This collaborative approach has enabled us to address longstanding challenges around connectivity, accessibility, and scalability in cryogenic environments. 

Looking ahead, ICE-Q is designed to evolve with the needs of the quantum ecosystem. Future modules targeting temperatures as low as 10 mK for superconducting systems are already in 
development—ensuring the platform remains aligned with the demands of a rapidly advancing field. 

As Paul adds: “This system introduces new avenues for hardware development that were previously constrained by existing cryogenics infrastructure. It ensures our clients can continue scaling without being bottlenecked by their cooling environment.” 

As quantum systems move from research to real-world deployment, scalable and maintainable infrastructure becomes critical. With ICE-Q, we are enabling faster deployment, reduced downtime, and a clear pathway to large-scale quantum integration.
