qiskit.chemistry.algorithms.ExcitedStatesSolver

class ExcitedStatesSolver

The excited states calculation interface

__init__()

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

Methods

__init__()	Initialize self.
solve(driver[, aux_operators])	Compute the excited states energies of the molecule that was supplied via the driver.

abstract 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
