Xanadu
Listed on Nasdaq and the TSX as XNDU on 23 March 2026 after a $3.1B SPAC merger
Quantinuum
Listed on Nasdaq as QNT on 4 June 2026, raising $1.68B at a $60 IPO price
IQM
Trading on Nasdaq as IQMX since 2 July 2026 after a $1.8B SPAC, the first European quantum company on a US exchange
Pasqal
SPAC business combination announced in August 2026 under the ticker PSQL, not yet trading
QuEra
96 logical qubits from 448 physical, which the platform's own FAQ calls the record as of September 2026

What the sector numbers tell you
Companies carry more than one sector label, because a superconducting hardware maker usually ships software and sells research services too. That is why the sector column adds up to more than the 1,213 mapped entities, and it is also what makes the breakdown useful, since it shows where commercial activity concentrates rather than how firms describe themselves.
Research organisations lead with 294, with hardware (273) and software (267) close behind. The component supply chain (210) is the quiet story, the picks-and-shovels layer that grows as the industry moves from laboratory demonstrations to manufactured systems.
Communications (181) and sensing (156) round out the applied layers, and post-quantum cryptography now has 132 companies of its own. Every sector label can be combined with a country filter on the map.

Who Uses Entangled Future
The same open dataset serves three kinds of reader, and each gets a number to start from.
Investors and analysts
Screen the 87 listed companies, follow the 418 investors and set private rounds against disclosed valuations, with the tracker stating which of its 230 deals carry a source.
Researchers and founders
See which companies build on your field and where they sit across 52 countries, with 176 research labs and universities on the platform’s dashboard alongside the companies.
Corporate strategy and policy
Find quantum-ready vendors, track competitor programmes and benchmark national ecosystems, with 110 enterprise adopters already on record.
Open Where the Rest of the Market Is Gated
Much of the market intelligence in this industry sits behind a sales call, an unpublished price list and a rounded number on a landing page. Entangled Future takes the opposite position: the full directory, map, investment tracker and technology stack are open to everyone, on day one, at no cost.
Openness also means exact figures rather than marketing counts. When this page says 1,225 companies and 87 listed companies, those are numbers you can click through and verify yourself. Cite them with attribution, and check the platform for the current figure before you publish, because they move.
Where the Data Comes From
Every profile is compiled from primary public sources. Entangled Future’s analysts track company announcements, stock-exchange and regulatory filings, funding disclosures and national quantum programme documents, and the platform says entries are checked against those sources before they are published.
Each record captures where a company is based, what it builds and the sectors it operates in. Of the 1,225 entities in the directory, 1,213 carry verified locations and appear on the map.
The platform says where its own evidence runs out. Its investment tracker notes that 95 of its 230 funding deals carry no source yet and asks readers to treat those as claims rather than records, which is the standard we hold our own reporting to.
Who Runs Entangled Future
Entangled Future is a quantum market intelligence company, and it builds and operates the platform itself. Its analysts maintain the dataset: 1,225 entities across 52 countries, 418 investors, 176 research labs, 87 listed companies and a running record of funding rounds and milestones.
The platform says its dataset is refreshed daily as companies launch, close rounds or list on public markets. Quantum Zeitgeist draws on the same data in its company and country reporting, and the platform is free to use with no account required.

Does the directory include universities and government labs?
The platform's dashboard counts 176 research labs and universities, and 294 of the entities in its map data carry the research label. The platform does not say how far those two sets overlap, so this page never adds them together. Government activity shows up through funding and milestone records, from national programme awards to DARPA Quantum Benchmarking Initiative selections.
