Entanglement properties of the time evolution of local operators in the Heisenberg picture are characterized using a measure Operator Space Entanglement Entropy (OSEE). The growth of OSEE in temporal dynamics is related to the number of Majorana fermions (index) in initial product operators, furthermore, it diverges logarithmically for infinite-index initial operators with the prefactor given by the number of stationary points in the quasi-particle dispersion relation. This property is connected to the quantum phase transition in the XY model far from the equilibrium.
