abstract evolve(evolution_problem)

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

Evolves an initial state $|\Psi\rangle$ for an imaginary time $\tau$ 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
