qiskit.algorithms.PVQD.evolve

PVQD.evolve(evolution_problem)[source]

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

Evolves an initial state \(|\Psi\rangle\) for a time \(t\) under a Hamiltonian \(H\), as provided in the evolution_problem.

Parameters

evolution_problem (TimeEvolutionProblem) -- The evolution problem containing the hamiltonian, total evolution time and observables to evaluate.

Returns

A result object containing the evolution information and evaluated observables.

Raises
  • ValueError -- If aux_operators provided in the time evolution problem but no estimator provided to the algorithm.

  • NotImplementedError -- If the evolution problem contains an initial state.

Return type

TimeEvolutionResult
