Quantum measurements, information and entropy production

In order to understand the Landau-Lifshitz conjecture on the relationship b etween quantum measurements and the thermodynamic second law, we discuss th e notion of "diabatic" and "adiabatic" forces exerted by the quantum object on the classical measurement apparatus. The notion of heat and work in mea surements is made manifest in this approach and the relationship between in formation entropy and thermodynamic entropy is explored.
