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 universalclass of systems. The violation is related to incompatibility between exponential decay and unitaryevolution, and as such are closely related to the quantum Zeno effect. The phenomenon can be experimentallyobserved by a continuous weak measurement.
