Abstract
A quantum system is investigated which consists of a two-state spin which interacts with a model apparatus consisting of a large number of bosons. The Hamiltonian which describes the interaction of system and apparatus is defined and the evolution of an initial state of the two by means of an evolution operator over time is calculated. Some insights into the nature of such measurement processes can be made.
