Our trapped ion quantum computers and software solutions are the highest performing in the industry, enabling our users to solve industry's most complex problems.

Our trapped ion quantum computers and software solutions are the highest performing in the industry, enabling our users to solve industry's most complex problems. Helios has the highest average two-qubit gate fidelity of any commercial quantum computer in the industry. * Quantum and AI can make each other stronger. AI discovers new quantum algorithms; quantum sharpens AI's data. See it with NVIDIA, AWS, and Hiverge. Working across industries to turn quantum computing into practical advantage. Helios is the most accurate commercial quantum computer in the world based on average two-qubit gate fidelity *, with a clear roadmap to Sol, Apollo, and beyond. From our unified cloud platform Nexus to our developer suite (Guppy, TKET, and HUGR), build on an integrated stack designed for accessibility. InQuanto is our domain-specific software library that enables users to run chemistry and materials workflows. “We have been exploring quantum computing for many years. Together with partners such as Quantinuum, we translate advances in quantum hardware into real‑world applications, including materials optimization, supporting the development of future vehicle generations.” Quantinuum and bp are

As reported in public records reported — not modeled.

Solid bars are reported offering amounts reported; hatched bars are the modeled post-money valuation est. — both on one shared scale so you can read raise-vs-worth at each round directly. Use the toggles to overlay data labels and the niche-peer / market average value lines.

Round size and date are reported; the stage label is inferred from round size (latest is Growth/Late — a round over $400M). Valuation is modeled from stage benchmarks scaled by the software/compute sector profile. Directional, not a quoted figure.

Benchmarked against 1370 companies in Computers. Each bar is a median (the middle company, not an average — outliers don't skew it). Two yardsticks: real money raised (reported on Form D) and modeled value (our estimate est.). These are whole-sector medians across all stages, except the per-stage row.

Raised more than 100% of sector peers (real $). Modeled value above 100% of peers (estimate).

Stage is inferred from round size est., not reported on the filing — a round's dollar size maps to a bucket: Pre-Seed <$1.0M · Seed $1.0M–$4.0M · Series A $4.0M–$15M · Series B $15M–$40M · Series C $40M–$100M · Series D+ $100M–$400M · Growth/Late >$400M.

Step-up, pace versus the sector's normal cadence, and revenue/exemption moves — read straight from the reported round facts reported.

Predictive signals are modeled est. from this company's own cadence and step-up, plus sector benchmarks — directional, not advice. Peer set and a CSV export live in your analyst workspace.

Officers, directors and promoters named in this company's public recordsreported — the people who run it (not its investors). "Also runs" counts come from name-matching across all records, so verify before acting.

Quantinuum is an official record sourced from the U.S. Securities and Exchange Commission (SEC). U.S. data is aggregated from SEC Form D filings.

Nearest neighbours across the whole database — matched on sector, stage and capital scale, and on shared operators (officers or directors named at both companies in public filings). A discovery shortlist, not a valuation cohort — verify before acting, the same way modeled figures are directional.

Matched by meaning, not labels — a local language model reads each company's name, sector and description and ranks the closest in that learned space. This catches look-alikes that cross sector boundaries; the structured list above explains its matches, this one trusts the text. Directional, like every modeled signal here.
