class MinimumEigensolver

The Minimum Eigensolver Interface.

Algorithms that can compute a minimum eigenvalue for an operator may implement this interface to allow different algorithms to be used interchangeably.

abstract __init__()

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__()	Initialize self.
compute_minimum_eigenvalue([operator, …])	Computes minimum eigenvalue.
supports_aux_operators()	Whether computing the expectation value of auxiliary operators is supported.

Attributes

aux_operators	Returns the auxiliary operators.
operator	Return the operator.

abstract property aux_operators

Returns the auxiliary operators.

Optional[List[Optional[OperatorBase]]]

abstract compute_minimum_eigenvalue(operator=None, aux_operators=None)

Computes minimum eigenvalue. Operator and aux_operators can be supplied here and if not None will override any already set into algorithm so it can be reused with different operators. While an operator is required by algorithms, aux_operators are optional. To ‘remove’ a previous aux_operators array use an empty list here.

매개변수

• operator (Union[OperatorBase, LegacyBaseOperator, None]) – If not None replaces operator in algorithm

• aux_operators (Optional[List[Union[OperatorBase, LegacyBaseOperator, None]]]) – If not None replaces aux_operators in algorithm

classmethod supports_aux_operators()

Whether computing the expectation value of auxiliary operators is supported.

If the minimum eigensolver computes an eigenstate of the main operator then it can compute the expectation value of the aux_operators for that state. Otherwise they will be ignored.

반환 형식

bool

반환값

True if aux_operator expectations can be evaluated, False otherwise
