qiskit.algorithms.gradients.SPSAEstimatorGradient.run¶
- SPSAEstimatorGradient.run(circuits, observables, parameter_values, parameters=None, **options)¶
Run the job of the estimator gradient on the given circuits.

circuits (Sequence[QuantumCircuit]) – The list of quantum circuits to compute the gradients.
observables (Sequence[BaseOperator | PauliSumOp]) – The list of observables.
parameter_values (Sequence[Sequence[float]]) – The list of parameter values to be bound to the circuit.
parameters (Sequence[Sequence[Parameter] | None] | None) – The sequence of parameters to calculate only the gradients of the specified parameters. Each sequence of parameters corresponds to a circuit in
circuits. Defaults to None, which means that the gradients of all parameters in each circuit are calculated. None in the sequence means that the gradients of all parameters in the corresponding circuit are calculated.options – Primitive backend runtime options used for circuit execution. The order of priority is: options in
runmethod > gradient’s default options > primitive’s default setting. Higher priority setting overrides lower priority setting

The job object of the gradients of the expectation values. The i-th result corresponds to
circuits[i]evaluated with parameters bound asparameter_values[i]. The j-th element of the i-th result corresponds to the gradient of the i-th circuit with respect to the j-th parameter.- Lève
