Rigetti Computing

Rigetti Computing is a full-stack quantum computing company that builds superconducting quantum processors and delivers access to them through Quantum Cloud Services (QCS). Developers program Rigetti quantum processing units (QPUs) with the Quil quantum instruction language via the open-source pyQuil SDK, compile with quilc, and simulate locally with the Quantum Virtual Machine (QVM). The QCS HTTP API (api.qcs.rigetti.com) exposes REST-style operations for quantum processors, instruction set architectures, engagements, endpoints, reservations, groups, billing, and account management, secured with OAuth2 (Okta) JWT bearer tokens. This profile was seeded as a VC-portfolio lead and enriched by the API Evangelist pipeline from Rigetti's public QCS OpenAPI, SDKs, and developer documentation.

Rigetti Computing publishes 9 APIs on the APIs.io network, including account API, authentication API, clientApplications API, and 6 more. Tagged areas include Company, Quantum Computing, Quantum Cloud, Developer Tools, and SDK.

Rigetti Computing’s developer surface includes authentication, sandbox, documentation, API reference, getting-started guide, support, engineering blog, and 19 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
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/rigetti-computing: open an issue to ask a question, or submit a pull request to add artifacts.
