    "abstract": "We propose a simple scheme for complete Bell-state measurement of photons\nusing hyperentangled states - entangled in multiple degrees of freedom. In\naddition to hyperentanglement, our scheme requires only linear optics and\nsingle photon detectors, and is realizable with current technology. At the cost\nof additional classical communication, our Bell-state measurement can be\nimplemented non-locally. We discuss the possible application of these results\nto quantum dense coding and quantum teleportation.",
