Run an experiment (circuit) and return a single experiment result.

        Args:
            experiment (QobjExperiment): experiment from qobj experiments list

        Returns:
            dict: A result dictionary which looks something like::

                {
                "name": name of this experiment (obtained from qobj.experiment header)
                "seed": random seed used for simulation
                "shots": number of shots used in the simulation
                "data":
                    {
                    "unitary": [[[0.0, 0.0], [1.0, 0.0]],
                                [[1.0, 0.0], [0.0, 0.0]]]
                    },
                "status": status string for the simulation
                "success": boolean
                "time taken": simulation time of this single experiment
                }

        Raises:
            BasicAerError: if the number of qubits in the circuit is greater than 24.
            Note that the practical qubit limit is much lower than 24.
