Xanadu is a Toronto-based photonic quantum computing company building cloud-accessible continuous- variable quantum processors based on squeezed states of light. Founded in 2016 by Christian Weedbrook and listed on TSX/Nasdaq (XNDU), Xanadu demonstrated a 50-million-fold Gaussian-boson-sampling speedup with Borealis in 2022 and published modular networked photonic quantum computing in Nature in 2025. Beyond hardware, Xanadu is one of the most prolific open-source contributors in quantum software — it maintains PennyLane (the de-facto cross-platform quantum ML framework), Strawberry Fields, MrMustard, The Walrus, Blackbird, Catalyst, Lightning, and FlamingPy, all under Apache-2.0. Xanadu's own Quantum Cloud was retired in January 2026; the company's developer surface is now centered entirely on its open-source stack and integrations with third-party QPUs.
Xanadu publishes 10 APIs on the APIs.io network. Tagged areas include Quantum Computing, Photonic Quantum Computing, Quantum Machine Learning, Continuous Variable, and Open-Source.
The Xanadu catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
Xanadu’s developer surface includes developer portal, documentation, engineering blog, YouTube channel, training material, code examples, release notes, and 13 more developer resources.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/xanadu: open an issue to ask a question, or submit a pull request to add artifacts.
