note

The model is invariant under rotations around the z axis so it is a natural candidate for a PCC. We also analyzed the case in which the XY symmetry is broken, the results for the fidelity were always much worse than for XY or Heisenberg models.

note

To find the evolution for the initial state, Eq. (2), we need to express it in the eigenstate basis. After some simple algebra one finds that |00...0〉=|(M+1)/2, (M+1)/2〉 and |10...0〉 = 1/√1+M|(M+1)/2, (M-1)/2〉-√M/√1+M|(M-1)/2, (M-1)/2〉.
