Bases: `qiskit.primitives.base.base_primitive.BasePrimitive`
|
||
|
||
Sampler base class
|
||
|
||
Base class of Sampler that calculates quasi-probabilities of bitstrings from quantum circuits.
|
||
|
||
**Parameters**
|
||
|
||
* **circuits** – Quantum circuits to be executed.
|
||
* **parameters** – Parameters of each of the quantum circuits. Defaults to `[circ.parameters for circ in circuits]`.
|
||
* **options** – Default options.
|
||
|
||
**Raises**
|
||
|
||
**ValueError** – For mismatch of circuits and parameters list.
|
||
|
||
## Methods
|
||
|
||
### close
|
||
|
||
<Function id="qiskit.primitives.BaseSampler.close" signature="BaseSampler.close()">
|
||
Close the session and free resources
|
||
</Function>
|
||
|
||
### run
|
||
|
||
<Function id="qiskit.primitives.BaseSampler.run" signature="BaseSampler.run(circuits, parameter_values=None, **run_options)">
|
||
Run the job of the sampling of bitstrings.
|
||
|
||
**Parameters**
|
||
|
||
* **circuits** – One of more circuit objects.
|
||
* **parameter\_values** – Parameters to be bound to the circuit.
|
||
* **run\_options** – Backend runtime options used for circuit execution.
|
||
|
||
**Returns**
|
||
|
||
The job object of the result of the sampler. The i-th result corresponds to `circuits[i]` evaluated with parameters bound as `parameter_values[i]`.
|
||
|
||
**Raises**
|
||
|
||
**ValueError** – Invalid arguments are given.
|
||
</Function>
|
||
|
||
### set\_options
|
||
|
||
<Function id="qiskit.primitives.BaseSampler.set_options" signature="BaseSampler.set_options(**fields)">
|
||
Set options values for the estimator.
|
||
|
||
**Parameters**
|
||
|
||
**\*\*fields** – The fields to update the options
|
||
</Function>
|
||
|
