          This method returns a result which allows access to the entire
          wave function.
  
          Args:
              program: The circuit or schedule to simulate.
              param_resolver: Parameters to run with the program.
              qubit_order: Determines the canonical ordering of the qubits. This
                  is often used in specifying the initial state, i.e. the
                  ordering of the computational basis states.
              initial_state: The initial state for the simulation. The  form of
                  this state depends on the simulation implementation.  See
                  documentation of the implementing class for details.
  
          Returns:
              SimulationTrialResults for the simulation. Includes the final state.
