Alice Bob

Alice & Bob is a quantum computing company headquartered in Paris with a presence in Boston, founded in 2020, building a universal fault-tolerant quantum computer on cat qubits — superconducting qubits that are intrinsically protected against bit-flip errors. Its commercial developer surface is Felis Cloud, a Quantum Computing as a Service (QCaaS) product that executes quantum circuits on Boson 4 cat-qubit QPUs hosted in Alice & Bob's own premises and on cloud-hosted physical and logical qubit emulators. Felis Cloud is reached through a public REST API (jobs, targets, availability and health) that accepts circuits in QIR format, and through the open-source qiskit-alice-bob-provider Qiskit provider that wraps it.

Alice Bob publishes 3 APIs on the APIs.io network: Health API, Jobs API, and Targets API. Tagged areas include Company, Quantum Computing, Quantum, Cloud Computing, and Emulation.

Alice Bob’s developer surface includes documentation, API reference, getting-started guide, support, pricing, signup flow, changelog, and 21 more developer resources.

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/alice--bob: open an issue to ask a question, or submit a pull request to add artifacts.
