Three dated rows trace a private-to-public transition, so the profile is best read as a timeline of financing instruments rather than a growth curve.
This profile is a single-company view of the same public ledger that builds the global ranking. Figures are disclosed amounts, not valuations; an empty cell means the source did not publish a number.

JPMorgan Chase led this ~$300M Series B, a notable example of a financial institution taking a lead position in full-stack trapped-ion hardware. Quantinuum combines processors with a commercial software and services business, so a single financing supports two very different cost structures. Our ledger keeps the amount as one row but flags that its disclosed total is less directly comparable with pure hardware vendors.
A ~$600M growth round without a Series letter usually signals an extension into commercial scale rather than a new technology milestone. For Quantinuum, which sells hardware plus software and services, that label fits a company broadening distribution after its 2024 Series B. Reuters is the cited source, and the row sits in the same quarter as the largest photonic raise, which is why 2025 dominates the dataset's annual concentration.
The ~$1.7B attached to a reported 2026 IPO is the largest single figure in our dataset, and it is public-market proceeds rather than venture capital. Quantinuum had a JPMorgan-led Series B in 2024 and a growth round in 2025; this listing closes a three-year transition from private full-stack developer to public company. Because the report is auto-collected, we show the source URL and keep the amount flagged as approximate until a filing is matched.
The 2026 IPO is a reported offering size. Because no post-money valuation was published with it, the profile records proceeds only and leaves valuation out.
