    "abstract": "It is shown that quantum-type coherence, leading to indeterminism and\ninterference of probabilities, may in principle exist in the absence of the\nPlanck constant and a Hamiltonian. Such coherence is a combined effect of a\nsymmetry (not necessary physical) and semantics. The crucial condition is that\nsymmetries should apply to logical statements about observables. A theoretical\nexample of a non-quantum system with quantum-type properties is analysed.",
