    "abstract": "Coupled pair of PT-symmetric square wells is studied as a prototype of a\nquantum system characterized by two manifestly non-Hermitian commuting\nobservables. We demonstrate that there exists a domain of couplings where both\nthe respective sets of eigenvalues (viz., energies and spin projections) remain\nreal and where the model acquires a consistent probabilistic interpretation\nmediated by an `ad hoc\u0027 scalar product.",
