SciPyRealEvolver

class SciPyRealEvolver(num_timesteps)

Bases: RealTimeEvolver

Classical Evolver for real time evolution.

Evolves an initial state $|\mathrm{\Psi }⟩$ for a time $t$ 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 steps is not a positive integer.

Methods

evolve(evolution_problem)

Perform real time evolution $\exp (-itH)|\mathrm{\Psi }⟩$.

Evolves an initial state $|\mathrm{\Psi }⟩$ for a time $t$ 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
