    "abstract": "A complete and deterministic Bell state measurement was realized by a simple\nlinear optics experimental scheme which adopts 2-photon polarization-momentum\nhyperentanglement. The scheme, which is based on the discrimination among the\nsingle photon Bell states of the hyperentangled state, requires the adoption of\nstandard single photon detectors. The four polarization Bell states have been\nmeasured with average fidelity $F=0.889\\pm0.010$ by using the linear momentum\ndegree of freedom as the ancilla. The feasibility of the scheme has been\ncharacterized as a function of the purity of momentum entanglement.",
