STL Partners attended the launch of QIC to explore what it will take to deploy quantum technologies in real-world data-centre environments.

Introduction

Last week, STL Partners was invited to the launch of the Quantum Infrastructure Council (QIC) in London, a new initiative focused on the practical realities of deploying quantum technologies in data-centre and digital infrastructure environments.

The event brought together perspectives from across the quantum, data-centre, technology and financial-services ecosystems. Below are our key takeaways from the launch, including why quantum infrastructure is becoming a more urgent topic, where early demand may emerge, and what still needs to be solved before deployment can scale.

Quantum needs an infrastructure conversation before commercial maturity

A central theme of the event was the maturity of the quantum computing market. The technology continues to show significant promise, with progress across hardware, control systems, software, error correction and hybrid integration. Investment and partnerships are also helping to move the sector from a primarily research-led environment towards a more structured commercial ecosystem.

However, the market remains at an early stage. Quantum computing has not yet reached widespread commercial adoption, and many potential use cases are still being explored rather than deployed at scale. For most enterprises, the question is not whether quantum may become important, but when it will deliver clear, repeatable value in real operational settings. Thus, QIC’s message was not suggesting that every data centre should prepare to host quantum hardware immediately. Rather, it recognises that infrastructure planning cycles are long, and that the foundations for future deployment models need to be considered before demand is fully established.

The data-centre industry has seen similar transitions before. New infrastructure categories often begin with pilots, specialist requirements and bespoke deployments. Over time, the market identifies which requirements are exceptional, which can be absorbed into existing operating models, and which need to be standardised. Quantum appears to be entering that early phase: commercially immature, but sufficiently credible for the infrastructure ecosystem to begin preparing.

Where quantum demand may emerge first: financial services

Vishal Shete, Co-Founder and CEO of Qubitra, opened the first external presentation of the event, bringing the discussion closer to the demand side of the quantum market. Qubitra is a startup funded by Fujitsu and Standard Chartered, focused on developing quantum and frontier-technology applications for financial services.

Shete positioned financial services as one of the sectors where quantum computing could have early commercial relevance. Many of the industry’s core challenges are computationally intensive, commercially sensitive and highly dependent on small improvements in performance. The examples discussed included algorithmic trading, market making, fraud detection, portfolio optimisation, risk modelling and enhanced credit scoring. The presentation also drew a useful comparison with earlier technology shifts in finance. Machine learning changed the way financial institutions approached modelling and prediction, while optical fibre and colocation became central to the development of high-frequency trading. In both cases, infrastructure was not simply a supporting layer; it became part of the competitive model.

A similar dynamic may emerge around quantum over time. If financial institutions are to use quantum capabilities for material workloads, access will need to meet the standards expected in a regulated and security-conscious industry. Performance will matter, but so will resilience, governance, integration and proximity to existing compute and data environments.

Building the UK ecosystem around quantum technology

Sara Duodu, Programme Manager for Quantum and Digital Twins at techUK, placed the discussion in the context of the UK’s wider quantum ecosystem. techUK represents a broad base of technology companies across the UK, and its role in quantum is focused on convening industry, supporting policy engagement and helping create the conditions for emerging technologies to scale.

Duodu’s presentation highlighted that the UK has strong foundations in quantum. These include sustained public investment (totalling over £3bn committed to date), an active base of quantum companies, established research strengths and growing international partnerships. However, the presentation also made clear that early advantage does not automatically translate into long-term leadership.

To scale, the ecosystem will need more than scientific capability, including access to suitable infrastructure, stronger alignment between public and private capital, a deeper talent pipeline, clearer demand signals from end users, and partnerships that connect the UK ecosystem to international markets. Clusters will also be important, but only if they bring together companies, research institutions, investors and customers in ways that support commercial deployment rather than isolated innovation.

There is no single quantum computer

One of the most important infrastructure messages came from David Snelling, Co-Founder of QIC ( formerly Director of Advanced Compute at Fujitsu’s Centre for Cognitive and Advanced Technologies): there is no single “quantum computer.”

Different quantum modalities have different physical and operational requirements. Some require dilution refrigerators and millikelvin cooling. Some are highly sensitive to vibration. Some have magnetic sensitivity. Some need cryogenic maintenance, EMI shielding, precision environmental control or very stable uninterrupted power. Others may look closer to conventional infrastructure, but still require specialist control systems, networking, calibration and integration.

This matters because “quantum readiness” cannot be a generic label. A site that is suitable for one kind of quantum system may not be suitable for another. A deployment model that works for a superconducting system may not map neatly to trapped ions, photonics, neutral atoms or diamond vacancy approaches – see STL Partners’ article on quantum data centres for further detail on the complications of such infrastructure. Ultimately, the industry needs a more granular vocabulary. Rather than asking whether a data centre is quantum-ready, operators and customers need to ask: quantum-ready for what modality, at what scale, under what service model, and with what operational responsibilities?

What it takes to put quantum inside a real data centre

The most concrete discussion of the event came in the case-study panel with Simon Phillips, CTO of Oxford Quantum Circuits (one of the worlds’ leading quantum computing organisations), and Charlie Bernard, now with Northern Data Group and formerly of CentreSquareDC (CSquare). Their discussion focused on their own practical experience together of deploying a quantum computer inside a wider data centre facility.

The objective of the deployment was not simply to place quantum hardware in a commercial building. It was to provide a quantum computing environment that could meet the resilience, security and operational expectations of enterprise customers. For organisations in sectors such as finance, defence, research and advanced industry, access to quantum capability will only be useful if it can sit within trusted infrastructure environments.

The panel made clear that this is not a straightforward exercise. Quantum systems do not always fit neatly into the assumptions that underpin conventional data-centre design. Standard facilities are largely organised around racks, power density, cooling, cabling, access and repeatable operating procedures. Early quantum systems can have very different requirements, particularly around physical footprint, specialist equipment, cryogenic systems and the boundary between the responsibilities of the facility operator and the quantum provider.

In the case discussed, one of the key challenges was space. The quantum system could not simply be treated as another rack of IT equipment. It required a different approach to layout and planning, while still needing to operate within an environment designed for security, resilience and availability. The significance of the deployment was that these issues were resolved in practice. It showed that quantum systems can be hosted in data-centre environments, provided the facility and quantum provider work closely enough to translate specialist technical needs into operational requirements.

This experience is becoming increasingly relevant as Oxford Quantum Circuits expands its data-centre deployment model. The company has since deployed quantum capability in Equinix’s TY11 facility in Tokyo and has announced a Quantum-AI data-centre initiative with Digital Realty and NVIDIA in New York. These examples point towards a future in which quantum systems are integrated alongside classical compute, AI infrastructure and high-performance networking, rather than existing as isolated research assets.

The rise of AI data centres may also create a more favourable environment for this kind of deployment. AI facilities are often designed around very high power densities, advanced cooling and dense compute environments. Quantum systems, by contrast, may place relatively lower demands on power but higher or less conventional demands on space, layout and specialist support. That difference creates a potential complementarity: facilities built for the next generation of AI and high-performance compute may also be well positioned to host quantum systems, particularly where spare space, secure environments and strong connectivity are available.

The longer-term ambition is to make these deployments more repeatable. Quantum will remain technically complex, but the aim is for more of that complexity to be packaged within the system and service model, reducing the burden on each individual facility. If quantum infrastructure is to scale, the industry will need to move from bespoke deployments towards clearer templates for how quantum systems are installed, operated and integrated into the broader digital infrastructure stack.

Conclusion

The launch of QIC underlined an important point: quantum infrastructure is not a problem to solve only once quantum computing reaches full commercial maturity. By then, the assumptions, standards and deployment models that shape the market may already be difficult to change. The opportunity now is to bring the relevant parts of the ecosystem together early. Quantum companies, data-centre operators, cloud providers, investors, standards bodies and enterprise users all have a role to play in defining what practical, secure and scalable quantum deployment should look like.

QIC has been created to support that process. By focusing on the real-world conditions for deploying, operating, financing and scaling quantum infrastructure, it can help the industry move beyond individual pilots towards clearer, more repeatable models. For organisations that expect quantum to become part of the future compute landscape, the message from the launch was clear: the technology may still be developing, but the infrastructure conversation has already begun.
