Quantinuum Ltd: Helios, the IPO and Why the Name Overlaps with QNT
The company
Quantinuum Ltd builds trapped ion quantum computers and software, led by President and CEO Rajeeb Hazra. Honeywell remains a major shareholder, and reports put its voting power after the listing at roughly 47 to 48 percent.
Helios
Quantinuum announced the commercial launch of Helios on November 5, 2025. It has 98 fully connected physical qubits, single-qubit gate fidelity of 99.9975 percent and two-qubit gate fidelity of 99.921 percent, with customers named as Amgen, BMW Group, JPMorganChase and SoftBank. A Python based language called Guppy lets developers mix quantum and classical code. The company earlier reported 48 logical qubits encoded in 98 physical qubits. See trapped ion computers.
The IPO
According to the company's pricing announcement, Quantinuum priced an upsized IPO of 28 million Class A shares at 60 dollars on June 3, 2026, with trading on the Nasdaq under the ticker QNT starting June 4. Coverage puts the proceeds at about 1.68 billion dollars and the implied valuation at roughly 15 billion dollars; exact valuation figures differ by outlet. The filing showed 30.9 million dollars of 2025 revenue and a 192.6 million dollar net loss, with one customer accounting for most of an early quarter's revenue.
Why the name overlap matters
The memecoin QUANTUM (QNT) on Solana is a separate, independent community token. It is not issued by, affiliated with, endorsed by or connected to Quantinuum Ltd or its Nasdaq shares. Buying one is not buying the other, and news about the company does not describe the token. Read the full comparison and always verify the contract address.

This site is about the whole quantum sector and a Solana memecoin themed around it, not any single company. See the innovators guide.
IPO details from the company's releases
The company's pricing release gave the offering as 28 million Class A shares at 60 dollars, expected to trade on the Nasdaq Global Market under QNT from June 4, 2026. Coverage reports gross proceeds of about 1.68 billion dollars, all from shares sold by the company, with an option for underwriters to buy up to 4.2 million more shares. J.P. Morgan and Morgan Stanley were joint lead book runners. Some outlets differ on the exact tier of the Nasdaq market and on release dates, so for any detail that matters, use the company's investor relations site at ir.quantinuum.com and the SEC's filings. We did not read the SEC filings directly.
What the technology claims mean
Trapped ion machines hold qubits as individual charged atoms. Their strength is accuracy: Quantinuum Ltd reported a two-qubit gate fidelity of 99.921 percent on Helios, and being fully connected means any qubit can interact with any other. The trade-off is speed and scale. Read more in Helios and logical qubits and how rivals approach ions.
Where Honeywell fits
Honeywell was the original parent and remains a major shareholder, as noted above. For the industrial and cybersecurity ecosystem around the company, see SandboxAQ and Honeywell.
Reading a quantum IPO
A listing raises money and attention, but it does not by itself show that the technology works at scale. Revenue, customers and cash burn tell more. See quantum IPOs and SPACs explained, government contracts as revenue and why valuations swing on news. Nothing here is a view on the company's shares, and this page is not investment advice.
If you landed here from a crypto search
Quantinuum Ltd and the Solana memecoin QUANTUM (QNT) are unrelated. The memecoin's contract address is on the QNT facts page, and company news does not describe it. Holders and the team should consult a lawyer on any trademark question.
