ExcitedStatesSolver#

class ExcitedStatesSolver[ソース]#

ベースクラス: ABC

The excited states calculation interface.

Attributes

solver#: Returns the solver.

Methods

abstract get_qubit_operators(problem, aux_operators=None)[ソース]#

Gets the operator and auxiliary operators, and transforms the provided auxiliary operators using a QubitMapper. If the user-provided aux_operators contain a name which clashes with an internally constructed auxiliary operator, then the corresponding internal operator will be overridden by the user-provided operator.

パラメータ:

problem (BaseProblem) – A class encoding a problem defining the qubit operators.
aux_operators (dict[str, qiskit_nature.second_q.operators.sparse_label_op.SparseLabelOp | qiskit.quantum_info.operators.symplectic.sparse_pauli_op.SparsePauliOp] | None) – Additional auxiliary operators to transform.

戻り値:

A tuple with the main operator (hamiltonian) and a dictionary of auxiliary default and custom operators.

戻り値の型:

tuple[qiskit_nature.second_q.operators.sparse_label_op.SparseLabelOp, dict[str, qiskit_nature.second_q.operators.sparse_label_op.SparseLabelOp] | None]

abstract solve(problem, aux_operators=None)[ソース]#

Compute the excited states energies of the molecule that was supplied via the driver.

パラメータ:

problem (BaseProblem) – A class encoding a problem to be solved.
aux_operators (dict[str, qiskit_nature.second_q.operators.sparse_label_op.SparseLabelOp | qiskit.quantum_info.operators.symplectic.sparse_pauli_op.SparsePauliOp] | None) – Additional auxiliary operators to evaluate.

戻り値:

An interpreted EigenstateResult. For more information see also interpret().

戻り値の型:
