Abstract

It is shown that, in the contect of an idealized macroscopic quantum coherence experiment, the prediction of quantum mechanics are incompattible with the conjunction of two general assimptions which are designated macroscopic realism and noninvasive measurability at the macroscopiclevel. The conditions under which quantum mechanics can be tested against these assumptions in a realistic experiment are discussed.
