Tracking venture financing across the world's quantum computing, quantum communication and quantum sensing companies — ranked by region and country, and by funding size in USD.
data updated 2026-11-06 · next scan daily 02:30 UTC5 companies appear on the same 2026-11 instrument with no priced value attached. Each notice keeps its own note on the timeline; none of them moves the funding totals.
A ~$140M Series D closes a visible Chinese financing ladder that started with a 2024 Series B and continued through a pre-IPO round the same spring. For SpinQ, the sequence matters more than any single figure: desktop NMR product revenue and a domestic listing path are different capital stories from cloud-only hardware peers. The amount is auto-collected with one duplicate merged, so we present it as an estimate and link the source.
The ~$300M reported raise for Atom Computing is best read beside the CHIPS Act letter of intent recorded later in 2026: one is private capital, the other a policy signal with no priced equity value. Neutral-atom systems moved from physics milestones to deployment commitments in a short window, so a round of this size usually funds infrastructure rather than a single record. A syndicated duplicate was merged and the figure is flagged approximate.
A ~$420M reported raise is roughly nine times the RMB-converted B+ round we recorded for Origin Quantum in 2023, a jump large enough that we keep it as one press figure and refuse to promote it into a confirmed cumulative total. Chinese-language coverage often bundles credit lines, subsidies and equity into one number, so the methodology keeps this row marked approximate. One syndicated duplicate was merged and the source URL is published.
Two overlapping reports of this ~$124M FD-SOI silicon-spin raise were merged, which is why the surviving row carries a corroborating count rather than a second timeline entry. Quobly is pursuing a foundry-compatible route, so the relevant comparison is with other CMOS-oriented European startups, not with photonic or trapped-ion totals. The figure remains approximate and auto-collected with its source link visible.
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.
A ~$200M reported raise barely a week after a January figure for the same company is exactly the pattern our publication-layer de-duplication is meant to expose: either two tranches, or one round reported twice. Photonic Inc. builds silicon spin-photon modules, where financing news is often syndicated across outlets. We keep the later, larger report with a corroborating count and flag it as approximate rather than adding both to the total.
This ~$61.6M Series A entry from news monitoring overlaps with a priced Series B the same company recorded in 2023, so the apparent stage regression is a data-quality warning rather than a real down-round. We keep it with an auto-collected badge and a merged duplicate count instead of silently deleting it. Readers should treat the amount as reported and check the source URL before citing the stage label.
A free, daily-updated ranking of quantum technology companies worldwide by disclosed funding — organized by region (China, United States, Europe, Asia-Pacific, Middle East), technology type (quantum computing, quantum communication, quantum sensing) and funding size in USD.
An automated pipeline scans public news sources daily and merges new funding events. Automatically collected items are clearly marked ⚡ auto until a human verifies them against the source.
Public announcements, regulatory filings and reputable press (Reuters, TechCrunch, company releases and more). All amounts are approximations with confidence levels — see the Methodology page.
Yes — the datasets are machine-readable JSON and licensed CC BY 4.0: companies.json, funding-events.json, stats.json. Attribution appreciated.
No. Informational only. Figures may be inaccurate or outdated — always verify with official sources before making decisions.
Hand-written analysis of how quantum funding is reported, counted and compared. Every page uses the same published dataset as the rankings.
Market prices, the people behind the technology, and daily observations — kept separate from the funding ledger on purpose.
Publicly traded quantum companies ranked by market value, with private companies in a separate comparison block so the two numbers are never added together.
Open section → NEWResearchers, engineers and founders whose work explains why a technology route or a financing round exists in the first place.
Open section → NEWOne hand-written observation per event, published only after a source check. Drafts never leave the editorial file.
Open section →Data status: market-cap figures are illustrative placeholders labelled DEMO, people entries are working notes labelled UNVERIFIED, and briefs tagged SAMPLE are format examples. Read the labels before citing anything.
