    "abstract": "The hybrid entangled states generated, e.g., in a trapped-ion or atom-cavity\nsystem, have exactly one ebit of entanglement, but are not maximally entangled.\nWe demonstrate this by showing that they violate, but in general do not\nmaximally violate, Bell\u0027s inequality due to Clauser, Horne, Shimony and Holt.\nThese states are interesting in that they exhibit the entanglement between two\ndistinct degrees of freedom (one is discrete and another is continuous). We\nthen demonstrate these entangled states as a valuable resource in quantum\ninformation processing including quantum teleportation, entanglement swapping\nand quantum computation with \"parity qubits\". Our work establishes an\ninteresting link between quantum information protocols of discrete and\ncontinuous variables.",
