SciPyImaginaryEvolver

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.

Parámetros:

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

Muestra:

ValueError – If num_timesteps is not a positive integer.

Methods
