qiskit.chemistry.algorithms.ExcitedStatesSolver¶

class ExcitedStatesSolver[source]¶

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)[source]¶

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
