TimeEvolutionResult¶

class TimeEvolutionResult(evolved_state, aux_ops_evaluated=None, observables=None, times=None)[source]¶

Bases: qiskit.algorithms.algorithm_result.AlgorithmResult

Class for holding time evolution result.

evolved_state¶

An evolved quantum state.

Type: QuantumCircuit|Statevector

aux_ops_evaluated¶

Optional list of observables for which expected values on an evolved state are calculated. These values are in fact tuples formatted as (mean, standard deviation).

Type: ListOrDict[tuple[complex, complex]] | None

observables¶

Optional list of observables for which expected on an evolved state are calculated at each timestep. These values are in fact lists of tuples formatted as (mean, standard deviation).

Type: ListOrDict[tuple[np.ndarray, np.ndarray]] | None

times¶

Optional list of times at which each observable has been evaluated.

Type: np.array | None

Parameters

evolved_state (QuantumCircuit | Statevector) – An evolved quantum state.
aux_ops_evaluated (ListOrDict[tuple[complex, complex]] | None) – Optional list of observables for which expected values on an evolved state are calculated. These values are in fact tuples formatted as (mean, standard deviation).
observables (ListOrDict[tuple[np.ndarray, np.ndarray]] | None) – Optional list of observables for which expected values for each timestep. These values are in fact tuples formatted as (mean array, standard deviation array).
times (np.ndarray | None) – Optional list of times at which each observable has been evaluated.

Methods

combine

Any property from the argument that exists in the receiver is updated.
