qiskit.chemistry.algorithms.ExcitedStatesSolver.solve

abstract ExcitedStatesSolver.solve(driver, aux_operators=None)

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

Parameters

• driver (BaseDriver) – a chemistry driver object which defines the chemical problem that is to be solved by this calculation.

• aux_operators (Union[List[FermionicOperator], List[BosonicOperator], None]) – Additional auxiliary operators to evaluate. Must be of type FermionicOperator if the qubit transformation is fermionic and of type BosonicOperator it is bosonic.

Return type

Union[ElectronicStructureResult, VibronicStructureResult]

Returns

an eigenstate result
