Bases: abc.ABC

Pending deprecation: 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The RealEvolver interface has been superseded by the qiskit.algorithms.time_evolvers.RealTimeEvolver interface.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.



abstract RealEvolver.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.

Return type
