Abstract. The Wave-Function Collapse is the decoherence of tangeled states of all points of the front of quantum-wave dissemination in space. The wave front of the quantum provides instantaneous and simultaneous transmission of the impulse of every point of the front to detector, and thus excludes the possibility of inducing of new wave fluctuating and dissemination. The synchronism of the change of states of the most distant points and points arbitrarily located on the front enables to convey the information through one single-quantum channel.
