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.

Arazzo Workflows

IBM Quantum Audit Workloads and Drill Into Job

List recent job-mode workloads from analytics, then pull the full job record and metrics for the most recent one.

ARAZZO

IBM Quantum Backend Readiness Preflight

Verify a backend is online, then gather its calibration properties and pulse defaults for circuit transpilation.

ARAZZO

IBM Quantum Cancel Running Job

Check a job's status and cancel it only if it is still queued or running.

ARAZZO

IBM Quantum Job Results and Logs

Poll a job to completion, then retrieve both its result payload and its execution logs.

ARAZZO

IBM Quantum List Jobs and Inspect

List recent jobs, then pull the full details and execution metrics for the most recent one.

ARAZZO

IBM Quantum Negotiate Version and List Backends

Discover the live API version, then list accessible backends and check one backend's status using that version.

ARAZZO

IBM Quantum Pause Session and Confirm

Read a session's state, toggle whether it accepts new jobs, and confirm the change.

ARAZZO

IBM Quantum Select Backend and Submit Job

List accessible backends, inspect a chosen backend's configuration, and submit a job to it.

ARAZZO

IBM Quantum Session Run and Close

Open a Qiskit Runtime session, run a job inside it, then close the session.

ARAZZO

IBM Quantum Submit Job and Poll Results

Submit a Qiskit Runtime primitive job, poll until it reaches a terminal state, and fetch the final result.

ARAZZO

IBM Quantum Tag Job and Verify

Replace a job's tags, confirm the change on the job, and search the tag catalog for one of them.

ARAZZO

IBM Quantum Usage-Aware Job Submission

Check instance usage and remaining limit before submitting a job, skipping submission when the limit is reached.
