We discuss the evolution of individual realizations of quantum superpositions conditioned by two distinct measurement schemes: amplitude (heterodyne) measurements and excitation number (counting) measurements. These two schemes result in either localization or quantum jumps in phase space, which we illustrate for some non-classical initial superpositions.
