BaseFermionBackend

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

Abstract base class for fermionic tweezer backends.

Initialize a backend class

Parameters:

• 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.

Raises:

AttributeError – if input field not a valid options

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

abstract 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.

Returns:

A options object with

default values set

Return type:

qiskit.providers.Options

BaseFermionBackend.options	Return the options for the backend
