SciPyImaginaryEvolver¶

class SciPyImaginaryEvolver(num_timesteps)[source]

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