Deprecated: Interface for Quantum Real Time Evolution.

The RealEvolver interface has been superseded by the qiskit.algorithms.time_evolvers.RealTimeEvolver interface. This interface will be deprecated in a future release and subsequently removed after that.

Deprecated since version 0.24.0

The class qiskit.algorithms.evolvers.real_evolver.RealEvolver is deprecated as of qiskit-terra 0.24.0. It will be removed no earlier than 3 months after the release date. Instead, use the interface qiskit.algorithms.time_evolvers.RealTimeEvolver. See in a new tab) for a migration guide.



abstract evolve(evolution_problem)

Perform real time evolution exp(itH)Ψ\exp(-i t H)|\Psi\rangle.

Evolves an initial state Ψ|\Psi\rangle for a time tt under a Hamiltonian HH, as provided in the evolution_problem.


evolution_problem (EvolutionProblem) – The definition of the evolution problem.


Evolution result which includes an evolved quantum state.
