## Is Cryogenic Cooling the Next Frontier for Data Centre Efficiency?

A $100 million philanthropic commitment anchors a partnership that could redefine how data centres manage heat — and it has its roots in quantum hardware.

Emergence Quantum, a University of Sydney spin-out founded in 2025, announced today a partnership with data centre giant AirTrunk to apply cryogenic cooling technology — the same engineering discipline that keeps superconducting qubits alive — to mainstream data centre infrastructure. The collaboration targets two specific pain points: reducing cooling water consumption and enabling gigawatt-scale renewable energy storage. Underpinning the initiative is a $100 million donation to the University of Sydney from the Khuda Family Foundation, established by AirTrunk Founder and CEO Robin Khuda.

The core thesis is straightforward: classical silicon chips run faster and more efficiently at low temperatures, but the economics of cryogenic cooling have historically confined the approach to niche applications — most obviously, quantum computers. The argument from both companies is that the scale of modern hyperscale data centres, combined with shrinking transistor geometries and the resulting heat dissipation challenge, has shifted that calculus. What was previously uneconomical is becoming viable at gigawatt scale.

Emergence Quantum's first commercial products, released in late 2025, focused on the cryogenic control systems and electronics that bridge qubits to classical software stacks. That same engineering capability, the company argues, is directly transferable to managing thermal loads in high-performance computing environments.

## What Emergence Quantum Actually Does

Emergence Quantum's core competency is the cryogenic control layer: the hardware that connects quantum processors to room-temperature classical systems. This is a genuine engineering bottleneck in quantum computing — [coherence time](https://quantumintel.tech/glossary/coherence-time) is partially determined by thermal noise introduced through control wiring, and every millikelvin of unwanted heat matters when you're trying to keep a transmon qubit coherent.

CTO Professor Thomas Ohki frames cryogenic data centres not as a speculative future state but as an engineering inevitability: "For us, cryogenic data centres are an inevitable reality — this cooling technology is needed for high-speed efficient silicon chips, superconducting logic, and ultimately quantum computing. All flavours of qubits need cryogenics one way or another."

That last point carries real weight. Whether you're operating transmon-based superconducting qubits (which require millikelvin temperatures near absolute zero), [neutral atom qubits](https://quantumintel.tech/glossary/neutral-atom-qubit) (which require laser cooling and vacuum systems), or photonic approaches — thermal management is a shared constraint. A company that builds cryogenic infrastructure at commercial scale for quantum systems gains directly applicable expertise for conventional HPC cooling, just at less extreme temperature ranges.

CEO Professor David Reilly was equally direct: "It's been understood for decades that computers run significantly faster and more efficiently in the cold, but there are challenges and costs to cooling that have so-far limited this approach to niche applications. The scale of data centres and tiny size of transistors today changes all that — the cryo-computing epoch has arrived."

## Australia's Structural Advantage — and Its Limits

The source material makes a specific claim worth examining: Australia's established expertise in large-scale cryogenic liquefied natural gas (LNG) infrastructure and emerging liquid hydrogen capabilities gives the country a structural head start in scaling cryo-data-centre technology. The abundant renewable energy base and existing decarbonisation experience are cited as complementary advantages.

This is a credible argument. Australia's LNG export industry has developed deep engineering competency in large-scale cryogenic containment and logistics — skills that are not trivially replicated. Transferring that industrial knowledge base to data centre cooling infrastructure is a plausible technology transfer path.

However, there's a skeptical read here. Cryogenic LNG operates at temperatures around -162°C. Quantum computing hardware — particularly superconducting qubits — requires millikelvin temperatures, orders of magnitude colder. The engineering overlap between LNG cryogenics and the deep-cold systems needed for quantum hardware is real but limited. For conventional silicon chip cooling, the temperature targets are far less extreme than either, sitting in a regime where the LNG expertise is more directly applicable. The partnership's immediate commercial focus appears to be on this conventional cooling use case, with quantum hardware infrastructure as a longer-term beneficiary.

University of Sydney Vice-Chancellor Professor Mark Scott characterised the collaboration as aiming to "bring about a new phase in data centre technology, one that is focused on hitting environmental milestones." The dual promise — reduced water consumption alongside gigawatt-scale energy storage integrated with renewable sources — is the kind of sustainability narrative that data centre operators are under increasing pressure to demonstrate. Whether the techno-economic models Emergence Quantum and AirTrunk aim to develop will validate that narrative at commercial scale is the critical open question.

## Industry Trajectory: What This Signals

This partnership is an early signal of a broader structural shift: quantum hardware companies accumulating cryogenic engineering expertise that becomes commercially valuable outside quantum computing itself. The [dilution refrigerator](https://quantumintel.tech/glossary/dilution-refrigerator) supply chain, cryogenic control electronics, and thermal management systems developed to support fault-tolerant quantum computing represent a genuine industrial capability — one that hyperscale data centre operators have reason to want access to.

For quantum hardware startups, this opens a non-obvious revenue path. Companies that have been building cryogenic infrastructure to serve a quantum computing market that remains pre-commercial at scale can potentially monetise that expertise against the immediate, large-scale demand from AI and HPC data centres. That's a meaningful business model hedge.

For AirTrunk and the broader data centre sector, the bet is that cryogenic cooling transitions from a quantum-specific curiosity to a mainstream efficiency tool as transistor density continues to increase and air cooling approaches its physical limits. If the techno-economic models hold, early movers in cryo-data-centre infrastructure gain a competitive advantage as the approach scales.

The Khuda Family Foundation's $100 million commitment to the University of Sydney provides an institutional anchor for the research needed to validate those models — and keeps the University of Sydney's quantum engineering ecosystem in the mix as a technical resource for both companies.

## Frequently Asked Questions

**What is Emergence Quantum and who founded it?**
Emergence Quantum is a spin-out from the University of Sydney, established in 2025. Its co-founders are Professor David Reilly (CEO) and Professor Thomas Ohki (CTO). The company designs and manufactures cryogenic control systems and electronics used to connect quantum processors to classical computing infrastructure.

**Why are cryogenic cooling and quantum computing connected?**
All major qubit modalities require some form of thermal management. Superconducting qubits (transmons) require near-absolute-zero temperatures — typically achieved with dilution refrigerators. The engineering discipline for managing these extreme cold environments is the same one Emergence Quantum is now proposing to apply to conventional data centre cooling, albeit at far less extreme temperature targets for classical chips.

**What is AirTrunk's role in this partnership?**
AirTrunk is a major data centre operator providing the deployment infrastructure and commercial scale. The company's founder and CEO Robin Khuda also established the Khuda Family Foundation, which has donated $100 million to the University of Sydney, providing an institutional research foundation for the collaboration.

**How does cryogenic cooling reduce data centre water consumption?**
The source material states this as a partnership objective but does not detail the specific mechanism. Traditional data centre cooling relies heavily on evaporative cooling towers that consume significant water. Cryogenic approaches using liquefied gases or closed-loop refrigerant systems can reduce or eliminate this dependence — though the operational economics at hyperscale are still being modelled.

**Does this partnership mean Emergence Quantum is moving away from quantum computing?**
No. Professor Ohki explicitly stated that cryogenic data centres are an "inevitable reality" needed for "superconducting logic, and ultimately quantum computing." The AirTrunk partnership extends the company's addressable market into conventional HPC cooling while the same technology roadmap supports quantum hardware infrastructure development.
