Xanadu

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 12 more developer resources.
