When quantum research stories make the news, our goal is to make them accessible to readers outside the lab. The Quantum Insider’s audience is broad and varied, so it’s important to translate the tricky, complex – and often counterintuitive – science behind these advances into clear, engaging stories that anyone can understand.
But, there’s another field that’s just as tricky, just as complex and, arguably, more counterintuitive than the spooky world of quantum — and that’s the even spookier world of finance.
Often (usually because these are breaking stories with meaningful immediate impact) we don’t take the time to translate this material for people who don’t know a SPAC from an IPO. In this piece, however, we’ll try ot break down Xanadu’s news that the company is bringing the company and photonic quantum technology to the public markets, as well as discuss the potential impacts of this move.
In an announcement yesterday, Xanadu Quantum Technologies plans to go public through a merger with Crane Harbor Acquisition Corp., a special-purpose acquisition company, in a deal valuing the Toronto-based startup at roughly $3 billion. If approved, it would make Xanadu the first publicly traded pure-play photonic quantum computing company and one of only a handful of quantum hardware firms to reach the public markets.
A special-purpose acquisition company, or SPAC, is a publicly traded shell firm that has already raised money through an IPO and merges with a private company, allowing that company to go public without a traditional stock offering.
What Is Actually Happening In The Deal
In this case, the publicly traded shell company is Crane Harbor and, under the agreement, the firm will merge with a newly formed entity that will combine with Xanadu. The resulting company is expected to list its shares on both the Nasdaq and the Toronto Stock Exchange. The transaction includes about $225 million from Crane Harbor’s trust account and an additional $275 million raised through a private placement from institutional investors, assuming no redemptions.
In the release, the companies talk about: “The transaction values Xanadu at a pre-money rollover equity value of US$3.0 billion.” What this means is that the deal assigns Xanadu a pre-money valuation of about US$3 billion, meaning that before any new capital is added, existing shareholders’ equity in the company is valued at that amount.
The $3 billion figure refers to Xanadu’s value before new funding, which can be confusing since the merged company is expected to debut at about $3.6 billion — roughly 20 percent higher. That higher estimate reflects the addition of about $500 million in new capital from investors and Crane Harbor’s cash reserves.
Current Xanadu shareholders will roll over all of their existing equity, receiving no immediate cash payout. The deal still requires shareholder and regulatory approval.
How Does The SPAC Structure Work
SPAC mergers, which a once-popular route for early-stage tech companies to access public capital, have become rarer after a wave of underperformance among post-merger companies. However, they allow firms like Xanadu to raise significant capital without a traditional IPO, but also expose them to heightened scrutiny if earnings or timelines disappoint.
SPAC mergers can offer faster access to capital and greater flexibility in setting terms. While a traditional IPO can take a year or more to complete, SPAC mergers can close in as little as a few months, making them attractive to young deep-tech firms eager to raise capital quickly.
| Aspect | SPAC Merger | Traditional IPO |
|---|---|---|
| Time to complete | A few months | Can exceed one year |
| Control over valuation | Negotiated directly | Market driven on listing day |
| Regulatory steps | Fewer initial hurdles | Extensive regulatory requirements |
| Capital raised | Comes from SPAC trust and PIPE | Raised through IPO roadshow |
| Attractiveness for early stage firms | High due to speed | Attractiveness for early-stage firms |
What Technology Is Xanadu Building And How Does Photonic Quantum Computing Work
Founded in 2016, Xanadu is betting on photonic quantum computing, a method that uses light particles, or photons, rather than superconducting loops or trapped ions to encode quantum information. Photons interact weakly with their environment, which helps preserve quantum coherence, and Xanadu’s systems operate at room temperature rather than near absolute zero.
Its latest “Aurora” machine connects multiple photonic modules through fiber-optic links, creating a networked and potentially scalable quantum computer. The company also develops PennyLane, an open-source software library that allows researchers to design and run quantum algorithms across different types of quantum hardware.
In 2022, Xanadu claimed “quantum supremacy” when its 216-qubit Borealis system performed a computational task in two minutes that would take a classical supercomputer millions of years – a feat that, while contested, is still significant for proving concept feasibility.
| Architecture | How it works | Key advantages | Main challenges |
|---|---|---|---|
| Photonic (Xanadu) | Uses photons to encode qubits | Room temperature operation, low noise, scalable modular design | Photon loss, generating high fidelity entanglement |
| Superconducting | Uses superconducting circuits | Well-funded, industry-leading prototypes | Needs extreme cooling, wiring complexity |
| Ion Trap | Traps ions with electromagnetic fields | Very stable qubits, long coherence | Difficult to scale hardware footprint |
| Quantum Annealing | Optimizes through energy landscapes | Good for specific problems | Well-funded, industry leading prototypes |
Why Does Xanadu’s Move To Go Public Matter?
So, why would a company want to go public anyway?
While going public is often confused with a way to instantly minting of new billionaires, there are more practical reasons for the move. Going public, for instane, gives Xanadu access to large-scale financing as it seeks to move from research prototypes to fault-tolerant quantum computers, which the company hopes will one day solve chemistry, materials and optimization problems beyond classical reach. The company says it aims to deliver a fault-tolerant system by 2029 with up to 1,000 logical qubits — an ambitious target requiring 100,000 physical qubits and sophisticated error correction.
For the broader industry, the listing marks a symbolic step: photonics joins superconducting, ion-trap, and annealing firms in the small circle of publicly traded quantum companies, alongside IonQ, Rigetti, and D-Wave. We might technically include Quantinuum in that group, as it is part of Honeywell a publicly traded company. However, investors anticipate that Quantinuum will eventually be spun out of Honeywell in its own IPO..
What Are The Main Potential Benefits Of Xanadu Going Public
Going public provides a company with access to broader investment capital and increased visibility, both of which can accelerate development timelines in capital intensive fields like quantum computing.
Everything equally blessed is equally cursed, as the elders say – and going public aptly fits that blessing-slash-curse.
On the upside, if successful, the deal could bring tangible benefits:
- Capital infusion: The combined $500 million could extend Xanadu’s runway through its next generation of hardware.
- Public visibility: Nasdaq and TSX listings may attract global partners and enterprise customers.
- Software leverage: With its PennyLane platform already used by nearly half of the quantum programming community, Xanadu could expand into training, consulting, and hybrid-cloud services.
A public listing also allows institutional investors to gain exposure to quantum computing through equity markets rather than venture funds, potentially accelerating capital flow into the sector.
Owning shares in a public company that are tracking higher is also a way to attract talent.
What Risks Could Affect Xanadu After Entering Public Markets
It’s important to clarify that there are risks and that SPAC deals have a checkered track record. Many post-merger tech companies have seen steep stock declines due to limited revenue, long development timelines, or overestimated market readiness. Xanadu remains pre-revenue in hardware and relies on research contracts and its software platform for income.
Quantum technology itself carries substantial technical risk. Achieving fault tolerance remains unsolved across all architectures. Photonic systems must still overcome losses in optical components and the difficulty of generating high-fidelity entangled photons at scale.
Public market volatility adds another unpredictable variable, especially for companies whose valuations depend heavily on long-horizon research milestones rather than near-term revenue.
Investors could value the stock on speculative expectations, exposing retail buyers to swings before the technology proves viable. For policymakers and analysts, the listing will also test how capital markets evaluate frontier science firms that are years away from commercial products.
There’s another broader investment consideration. Investor enthusiasm for quantum companies has lifted share prices across the sector, with public players like IonQ and D-Wave seeing strong market gains despite limited revenue. Yet new listings such as Xanadu’s could dilute that momentum — extending investor choice but pressuring valuations. The shift may ultimately benefit the sector by setting more realistic expectations and aligning valuations with technical progress rather than hype cycles.
A Look Into The Future and The Global Quantum Computing Landscape
The deal comes amid renewed competition in quantum hardware. U.S., European and Asian startups are operating in intensifying competitive conditions. Governments are pouring billions into national quantum initiatives to secure supply chains, talent and intellectual property. Investors are jumping into the fray, too, with billions of dollars exposed.
By combining photonics with open-source software and Canadian-U.S. dual listings, Xanadu is positioned one might say at a geopolitical and technological crossroads: a bridge between quantum research ecosystems and the public markets.
Whether investors embrace the listing will hinge on confidence that Xanadu can translate its scientific progress into revenue within this decade. If it succeeds, the company could validate photonics as a commercially viable path to scalable quantum computing. If not, the deal may become another reminder that public markets can struggle to price long-horizon technologies.
