    "abstract": "We study an influence of the continuous measurement in a composite quantum\nsystem C on the evolution of the states of its parts. It is shown that the\ncharacter of the evolution (decoherence or recoherence) depends on the type of\nthe measured quantity and on the initial state of the system. A number of\nconditions under which the states of the subsystems of C decohere during the\nmeasuring process are established. We propose a model of the composite system\nand specify the observable the measurement of which may result in the\nrecoherence of the state of one of the subsystems of C. In the framework of\nthis model we find the optimal regime for the exchange of information between\nthe parts of C during the measurement. The main characteristics of such a\nprocess are computed. We propose a scheme of detection of the recoherence under\nthe measurement in a concrete physical experiment.",
