QEOM¶

class QEOM(ground_state_solver, excitations='sd')[source]¶

Bases: qiskit.chemistry.algorithms.excited_states_solvers.excited_states_solver.ExcitedStatesSolver

The calculation of excited states via the qEOM algorithm

Parameters

ground_state_solver (GroundStateSolver) – a GroundStateSolver object. The qEOM algorithm will use this ground state to compute the EOM matrix elements
excitations (Union[str, List[List[int]]]) – The excitations to be included in the eom pseudo-eigenvalue problem. If a string (‘s’, ‘d’ or ‘sd’) then all excitations of the given type will be used. Otherwise a list of custom excitations can directly be provided.

Methods

Run the excited-states calculation.

Attributes

excitations¶

Returns the excitations to be included in the eom pseudo-eigenvalue problem.
