Aykunin I.N., Berdinsky V.L. QUANTUM MEASURING OF CONDITION AS IMPULSIVE FORCE OF COHERENT EVOLUTION AND "HEATING" OF MEASURING SYSTEMOn the example of two-level system it is shown that measuring instrument induces quantum evolution in measuring system, if operator of measured quantity does not commute with Hamiltonian which happens even if at the starting moment the system is in general condition. The authors suggest the solution of task about system transfer into orthogonal excited condition. Also they suggest two types of quantum evolution: oscillating and kinetic (nonoscillating), and also conditions of their appearance. It is confirmed that measuring instrument can increase the energy of non-singular system ("heat" it).
