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.
