Address, industry classification, listing and incorporation come from Xanadu Quantum Technologies's own SEC filer record, so the industry is the SEC's dry classification rather than a marketing label. The website was checked for this site against the company's own pages. The description was written for this site in August 2026 from Wikipedia: Xanadu Quantum Technologies, Xanadu Becomes First Pure-Play Photonic Quantum Computing Company to Go Public (The Quantum Insider) and Xanadu Announces First Quarter 2026 Results, not taken from any single article.

Description
Xanadu is a Toronto based quantum computing company that builds machines out of light rather than superconducting circuits, using squeezed states of photons in programmable Gaussian boson sampling processors that run at room temperature and are reached over the cloud. Founded in 2016 by Christian Weedbrook, who remains chief executive, it published a claimed quantum computational advantage result with its Borealis machine in 2022 and a Nature paper in 2025 on networking multiple photonic chips together, and it maintains the open source PennyLane framework for quantum machine learning and differentiable programming. Its stated goal is a photonic quantum data centre in Toronto by 2029, supported by Canadian and Ontario government funding and by partnerships with AMD, Lockheed Martin and Rolls-Royce. It listed on Nasdaq and the Toronto Stock Exchange under the ticker XNDU in March 2026 through a combination with Crane Harbor Acquisition Corp.

The full register, from 13F filings
The Register tab above is hand research: a dozen holders, each traced to the filing it came from. This asks the same question of the whole market for the quarter ended 31-mar-2026, where 41 managers reported a position. Broad where the research is deep, and shallow in the ways a 13F always is.
41 managers reported a position, together holding 19.9m shares, or 6.67% of the company. The 40 largest are listed. Percentages are of a share count taken later than this quarter, because the count in force at the snapshot is not published as a structured fact for this company. Where the count has moved since, the figures are off by that much.
Built from 13F filings, which report US listed, long, US custodied positions only. A register from this source is a floor rather than a level: a holder's true position can be far larger, as BlackRock's ASML stake shows at 1.28m shares in a 13F against 26.3m in its 13G/A. Holdings held through derivatives, outside US custody, or below a manager's reporting obligation do not appear. Where a holder is marked as a family, its total sums several separate filing entities and describes something no single filing describes; the constituent entities and their share counts are listed so the total can be checked. That roll-up can legitimately exceed the family's own Schedule 13G, because a 13G is filed by one legal entity: Vanguard reports Alphabet through ten advisory entities, and The Vanguard Group Inc itself reported zero after its January 2026 disaggregation.
What a reader needs to know to read these numbers
- Added 21 Aug 2026 under the newly listed company policy in data/listed.json. This company is not an S&P 500 constituent and is covered because it has a ticker and a CIK, not because of index membership.
- Shares outstanding is 297,993,837 as of 31 March 2026, from the company's own Form F-1 XBRL facts. Xanadu is a foreign private issuer and files 6-K and F-1 rather than 10-Q, so it reports no EntityCommonStockSharesOutstanding concept; the count comes from the company facts endpoint instead, which is still the filer's own number.
- Four of the 43 13F rows at CUSIP 98390R102 describe the subordinate voting Class B shares rather than the common, because those filers wrote the Class B under the common CUSIP. They are counted in this register, which is one register per CIK the same way the dual class constituents are handled.
- This company reached the site as a private company page because a 13F info table truncates the issuer to a fixed width, so it arrived as XANADU QUANTUM TECHNOLO LTD and matched nothing. The filed spelling is kept as an alias in ingest/registers.py.
- Holdings are NOT researched. This company was added for its ownership register under the newly listed policy, and the empty holdings list here means nobody has looked at what it owns, not that it owns nothing. The page says so rather than presenting an unexamined side as a sourced finding.
Looked for, not found
Recorded rather than filled in. Each of these is a place where a number could have been invented and was not.
- Market capitalisation, for the same reason.
