||
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]`.
|
||
|
||
**Raises**
|
||
|
||
**QiskitError** – For mismatch of circuits and parameters list.
|
||
|
||
