Abstract: A quantum decaying system can reveal its nonclassical behavior by being noninvasively measured. Correlations of weak measurements in the noninvasive limit violate the classical bound for a universal class of systems. The violation is related to incompatibility between exponential decay and unitary evolution, and as such are closely related to the quantum Zeno effect (QZE). The phenomenon can be observed together with QZE by a continuous weak measurement. Starting with the correlations mentioned above one could also estimate the coherence time of decay process.
