Description
qiskit is an agent skill for building, simulating, transpiling and executing quantum circuits with Qiskit and IBM Quantum Runtime. It uses the current Qiskit 2.x APIs to build circuits, prepare instruction set architecture circuits that suit real hardware, and run them through the version 2 primitives. The skill was reviewed on 1 October 2026 with local tests on qiskit 2.5.2, qiskit-ibm-runtime 0.50.0 and qiskit-aer 0.17.2. IBM account, quantum processor, session and batch examples are illustrative and were checked against documentation and source, not run, and no remote jobs were submitted. Runtime 0.50 deprecates the top-level SamplerV2 and EstimatorV2 implementations. New code imports Sampler from qiskit_ibm_runtime.executor_sampler and Estimator from qiskit_ibm_runtime.executor_estimator. These still implement the version 2 PUB interface, using client-side processing and an executor, and option models come from qiskit_ibm_runtime.options_models. The skill begins by helping you choose the right path for your task. Use it when you are writing or running Qiskit circuits, including on IBM hardware.…
