Xanadu targets quantum data centre in Toronto ahead of IPO

Canadian quantum computing company Xanadu Quantum Technologies plans to build its first quantum data centre in Toronto as it prepares for a highly anticipated public listing.

Founded a decade ago, the Toronto-based company has grown into one of North America's largest quantum specialists, employing around 260 people, with roughly 85 per cent based in the city, according to Founder and Chief Executive Officer, Christian Weedbrook, at the Toronto Region Board of Trade's Energy Symposium on January 29, 2026.

The firm is now working towards a public debut expected as early as this spring.

Xanadu's longer-term ambition is to deploy purpose-built quantum data centres worldwide, starting with its first build in Toronto. Weedbrook described a model based on compact facilities with a relatively small physical footprint, potentially covering the equivalent size of three to four tennis courts.

Each site would house hundreds of interconnected quantum server racks. Despite their modest size, such centres could tackle computational problems that would otherwise require hundreds or even thousands of conventional data centres.

For energy-intensive workloads, that difference is substantial. According to Xanadu's estimates, quantum systems could reduce energy requirements by two to three orders of magnitude compared with classical approaches.

Water usage, another concern for data centre operators, is expected to be broadly comparable to that of conventional facilities, while overall cooling needs are expected to be significantly lower due to the photonic architecture.

Xanadu's use of photonics underpins much of its competitive positioning. Photonic quantum systems rely on light transmitted through fibre optics, similar to the infrastructure already used across global telecommunications networks. That familiarity allows Xanadu to draw heavily on established manufacturing techniques rather than inventing entirely new components from scratch.

"It operates a telecom wavelength, and you can encode information on the laser to have broadband and have streaming and everything that you want," Weedbrook explained.. " I would look at it as laser pointer which we're all familiar with but we have to access the quantum properties of the laser pointer, and then it's really using a lot of stuff that comes from the telecommunication industry."

The approach also brings efficiency gains. Light-based systems generate less heat than electronic alternatives, reducing cooling requirements, which remain a significant challenge in quantum computing.

The company aims to deploy a large-scale version of its quantum data centre by around 2029 or 2030. While current systems operate at a small, proof-of-concept scale, Weedbrook said the challenge is no longer scientific uncertainty but engineering execution and capital constraints.

Through the upcoming merger with Crane Harbor Acquisition Corporation, the quantum firm announced a pro forma market capitalisation of approximately USD $3.6 billion.

As the company moves towards that IPO, Weedbrook said capital will be used to expand manufacturing capacity and scale production. While initial quantum data centres are expected to be more expensive to build, he claimed that costs should converge with traditional facilities as manufacturing volumes increase.

The planned Toronto quantum data centre also aligns with growing concerns around data sovereignty, Weedbrook added. As hyperscale cloud providers remain predominantly US-based, governments and enterprises are increasingly seeking domestic alternatives for sensitive data and advanced computing workloads.

Weedbrook said quantum computing could become a strategic component of national infrastructure over time.

Recent federal support reflects that shift. Xanadu has secured backing through Canada's Quantum Champions program, receiving up to CAD $23 million in funding to strengthen domestic capabilities.

Despite its global ambitions, Xanadu says it has no plans to relocate its headquarters. The company's workforce is drawn from around the world, but Toronto remains its operational core.

"We're not going anywhere," said Weedbrook. "Canada will always be our headquarters."
