**APIs profiled:** 9

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.
