    "abstract": "Decoherence of a quantum system (which then starts to display classical\nfeatures) results from the interaction of the system with the environment, and\nis well described in the framework of the theory of continuous quantum\nmeasurements (CQM). Reviewed are the various approaches to the CQM theory, and\nthe approach based on the effective complex Hamiltonians is discussed in\ngreater detail. The effective complex Hamiltonian is derived from the\nrestricted path integral, which emphasizes the role of information in the\ndynamics of the system being measured. The complex Hamiltonian is used for\nanalyzing the CQM of energy in a two-level system. Such measurement is\ndemonstrated to be capable of monitoring the quantum transition, and the back\neffect of monitoring on the probability of transition is analyzed. The\nrealization of this type of measurement by a long series of soft observations\nof the system is presented.",
