    "abstract": "Following on from previous work [J. A. Larsson, Phys. Rev. A 67, 022108\n(2003)], Bell inequalities based on correlations between binary digits are\nconsidered for a particular entangled state involving 2N trapped ions. These\ninequalities involve applying displacement operations to half of the ions and\nthen measuring correlations between pairs of corresponding bits in the binary\nrepresentations of the number of centre-of-mass phonons of N particular ions.\nIt is shown that the state violates the inequalities and thus displays\nnonclassical correlations. It is also demonstrated that it violates a Bell\ninequality when the displacements are replaced by squeezing operations.",
