Rigetti Computing

Rigetti Computing (Nasdaq, RGTI) is a Berkeley, California-based quantum computing company building superconducting quantum processors and the full-stack software needed to program and operate them. Founded in 2013 by Chad Rigetti, the company designs, manufactures, and operates multi-chip superconducting QPUs at its Fab-1 in Fremont, CA and offers cloud-based access through Quantum Cloud Services (QCS). Rigetti also sells the Novera QPU (9-qubit) for on-premises customers and provides Quantum Foundry Services for custom development. The current generation system Cepheus-1-108Q (107 qubits, deployed April 2026) is accessed via a hybrid REST + gRPC API surface, programmed using the open Quil instruction language, the pyQuil Python library, and the multi-language qcs-sdk (Rust core with Python bindings). Rigetti's hardware is also available indirectly through AWS Braket, Microsoft Azure Quantum, and as a Qiskit provider via qiskit-rigetti.

Rigetti Computing publishes 11 API contracts indexed on the APIs.io network, including Account API, Authentication API, Client Applications API, and 8 more. Tagged areas include Quantum Computing, Superconducting Qubits, Quantum Cloud Services, QCS, and QPU.

The Rigetti Computing catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Rigetti Computing’s developer surface includes authentication, developer portal, signup flow, documentation, getting-started guide, pricing, support, and 52 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Quantum Computing (hardware, cloud and software)	standard	44.1	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

name: Rigetti Computing
description: Rigetti Computing (Nasdaq, RGTI) is a Berkeley, California-based quantum computing company building superconducting
  quantum processors and the full-stack software needed to program and operate them. Founded in 2013 by Chad Rigetti, the
  company designs, manufactures, and operates multi-chip superconducting QPUs at its Fab-1 in Fremont, CA and offers cloud-based
  access through Quantum Cloud Services (QCS). Rigetti also sells the Novera QPU (9-qubit) for on-premises customers and provides
  Quantum Foundry Services for custom development. The current generation system Cepheus-1-108Q (107 qubits, deployed April
  2026) is accessed via a hybrid REST + gRPC API surface, programmed using the open Quil instruction language, the pyQuil
  Python library, and the multi-language qcs-sdk (Rust core with Python bindings). Rigetti's hardware is also available indirectly
  through AWS Braket, Microsoft Azure Quantum, and as a Qiskit provider via qiskit-rigetti.
