ibm-quantum

IBM Quantum is IBM's quantum computing program — the operator of the IBM Quantum Platform (quantum.cloud.ibm.com), the publisher of the open-source Qiskit SDK, and the provider of the Qiskit Runtime REST API for submitting Sampler and Estimator primitive jobs to 100+ qubit Heron-generation QPUs and managed simulators. The platform combines an Apache-2.0 software stack (Qiskit, qiskit-ibm-runtime, qiskit-ibm-catalog, Qiskit Aer, Qiskit Serverless, Qiskit Functions) with a tiered access model (Open / Pay-As-You-Go / Flex / Premium / On-Premises) and is the longest-running commercial quantum computing API surface in the industry.

ibm-quantum publishes 9 APIs on the APIs.io network, including Accounts API, Analytics API, Backends API, and 6 more.

The ibm-quantum catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

ibm-quantum’s developer surface includes authentication, developer portal, documentation, pricing, getting-started guide, sandbox, training material, and 49 more developer resources.

description: IBM Quantum is IBM's quantum computing program — the operator of the IBM Quantum Platform (quantum.cloud.ibm.com),
  the publisher of the open-source Qiskit SDK, and the provider of the Qiskit Runtime REST API for submitting Sampler and
  Estimator primitive jobs to 100+ qubit Heron-generation QPUs and managed simulators. The platform combines an Apache-2.0
  software stack (Qiskit, qiskit-ibm-runtime, qiskit-ibm-catalog, Qiskit Aer, Qiskit Serverless, Qiskit Functions) with a
  tiered access model (Open / Pay-As-You-Go / Flex / Premium / On-Premises) and is the longest-running commercial quantum
  computing API surface in the industry.
