About QuantumRoundup

What this site is

QuantumRoundup is a free, static, bilingual reference site that ranks quantum technology companies by cumulative disclosed financing. It covers three technology families — quantum computing, quantum communication (including QKD and quantum networks) and quantum sensing/metrology — across six regional groupings. Every page is pre-rendered HTML: there is no login, no paywall, no client-side rendering of the primary content, and no tracking script that a reader has to accept before seeing a table.

The underlying datasets are published as JSON under CC BY 4.0. That is deliberate. A ranking is an opinion about how to count, and the only honest way to publish an opinion about counting is to let anyone recount the numbers themselves. The company registry, the event ledger and the aggregates can all be downloaded and re-analysed.

Why it exists

Quantum funding headlines are hard to compare. One company announces a priced Series C; another announces an at-the-market equity programme drawn down over eighteen months; a third is listed as a beneficiary of a government letter of intent with no priced equity at all. Press coverage usually prints these as if they were the same kind of number, then sums them. Readers who want to understand the industry's capital structure are left with a total that is arithmetic but not meaningful.

We built this site to separate those capital types, label the uncertainty, and keep the primary source one click away. The ranking is therefore explicitly a capital ranking, not a technical benchmark, a valuation table or an investment recommendation. We say that on the ranking pages themselves rather than hiding it in a disclaimer.

How the editorial desk works

A daily automated scan of free public news feeds (Google News RSS and GDELT) looks for new financing reports and matches them against the company registry. Items that the pipeline finds on its own are published with an ⚡ auto badge and are not treated as verified. A human reviewer then checks the amount, the round label, the date and the primary source before the item loses that badge.

Several outlets routinely syndicate the same announcement with near-identical headlines. Showing each one as a separate event would inflate both the event count and the company totals. The publication layer therefore merges reports of the same round within a short window, keeps the best-sourced record and disclosures how many reports were merged. The raw ledger keeps all of them for provenance. This is a counting decision, and it is documented in the editorial policy rather than applied silently.

Published event text is rewritten into a short editorial note — amount, stage, named investors, and a hedged sentence about what the round means for that company's segment. It is not a copy of the news headline. Full details and the reasoning are on the methodology page.

What we deliberately do not do

• No paid placement. Companies cannot pay to appear, to move up, or to be described more favourably. There is no sponsored row and no affiliate link in the tables.
• No investment advice. A funding total says nothing about whether a company is a good investment, and we do not publish price targets, recommendations or promotional coverage.
• No invented precision. Where an amount is partially disclosed — common for RMB-denominated Chinese rounds — we convert approximately and treat the figure as a lower bound, marked with a tilde.
• No fabricated authorship. We do not invent named individual experts to lend authority to a dataset. The byline on every page identifies the responsible desk and shows the data cutoff and page-generation dates separately.
• No hidden collection. No accounts, no newsletter form, no first-party analytics profile and no cookie banner needed to read the site.

Who maintains it

The site is maintained by the QuantumRoundup Research Desk — a small editorial operation, not a fund, a broker, a vendor or a quantum hardware company. We have no commercial relationship with the companies in the tables. The project is an independent information service; the code and the data change history live in a public-style Git repository so that edits are auditable.

Because the dataset is small enough to inspect and the pipeline is deterministic, a single desk can maintain it. That is also why we publish a corrections log: when counting rules change, readers should be able to see when and why.
