Abstract :
The connection of quantum nondemolition observables with the symmetry operators of the Schr??dinger equation, is shown. The connection facilitates the construction of quantum nondemolition observables and thus of quantum nondemolition filters for a given system. An interpretation of this connection is given, and it has been found that the Hamiltonian description under which minimal wave pockets remain minimal is a special case of our investigation.
