    "abstract": "Quantum baker`s map is a model of chaotic system. We study quantum dynamics\nfor the quantum baker\u0027s map. We use the Schack and Caves symbolic description\nof the quantum baker`s map. We find an exact expression for the expectation\nvalue of the time dependent position operator. A relation between quantum and\nclassical trajectories is investigated. Breakdown of the quantum-classical\ncorrespondence at the logarithmic timescale is rigorously established.",
