- class SciPyImaginaryEvolver(num_timesteps)¶
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.
int) – The number of timesteps in the simulation.
ValueError – If num_timesteps is not a positive integer.
Perform imaginary time evolution \(\exp(-\tau H)|\Psi\rangle\).
