class qiskit.algorithms.SciPyImaginaryEvolver(num_timesteps)
Bases: ImaginaryTimeEvolver
Classical Evolver for imaginary time evolution.
Evolves an initial state for an imaginary time under a Hamiltonian , 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
