StatevectorSimulatorPy

class StatevectorSimulatorPy(configuration=None, provider=None, **fields)

Bases: QasmSimulatorPy

Python statevector simulator.

Initialize a backend class

Parameter

• configuration (BackendConfiguration) – A backend configuration object for the backend object.

• provider (qiskit.providers.Provider) – Optionally, the provider object that this Backend comes from.

• fields – kwargs for the values to use to override the default options.

Verursacht

AttributeError – if input field not a valid options

In addition to the public abstract methods, subclasses should also implement the following private methods:

classmethod _default_options()

Return the default options

This method will return a qiskit.providers.Options subclass object that will be used for the default options. These should be the default parameters to use for the options of the backend.

Rückgabe

A options object with

default values set

Rückgabetyp

qiskit.providers.Options

Methods

configuration	Return the backend configuration.
name	Return the backend name.
properties	Return the backend properties.
provider	Return the backend Provider.
run	Run qobj asynchronously.

options

Return the options for the backend

The options of a backend are the dynamic parameters defining how the backend is used. These are used to control the run() method.
