Sample a circuit on IBM hardware

ibm_quantum.run_sampler

Free up to 10 min/month; then $96/minute, billed per secondListed

Run a circuit with the Qiskit Runtime Sampler on one of IBM's real quantum computers and get measurement counts. Needs your own IBM Quantum API key.

Inputs

Name	Type	Description
`backend`required	string	Backend name, e.g. ibm_brisbane
`openqasm`required	string	OpenQASM 2 or 3 circuit source
`shots`	integer	default: 1024; range: 1 to …

Example output

Provider returns measured qubit results as counts (illustrative Bell pair: mostly "00" and "11").
