class qiskit.algorithms.SciPyImaginaryEvolver(num_timesteps)

Bases: ImaginaryTimeEvolver

Classical Evolver for imaginary time evolution.

Evolves an initial state $|\Psi\rangle$ for an imaginary time $\tau = it$ under a Hamiltonian $H$ , as provided in the evolution_problem. Note that the precision of the evolver does not depend on the number of timesteps taken.

Parameters

num_timesteps (int) – The number of timesteps in the simulation.

Raises

ValueError – If num_timesteps is not a positive integer.

Methods

evolve

evolve(evolution_problem)

Perform imaginary time evolution $\exp(-\tau H)|\Psi\rangle$ .

Evolves an initial state $|\Psi\rangle$ for an imaginary time $\tau$ under a Hamiltonian $H$ , as provided in the evolution_problem.

Parameters

evolution_problem (TimeEvolutionProblem) – The definition of the evolution problem.

Returns

Evolution result which includes an evolved quantum state.

Return type

TimeEvolutionResult
