对量子系统的一系列频繁测量（类似芝诺的测量）被证明会导致另一个量子系统与前者相互作用的“净化”。即使测量是在前一个系统上进行的，只要满足某些条件，它们的效果就会促使后者进入纯状态，无论其初始（混合）状态如何。
A series of frequent measurements on a quantum system (Zeno-like measurements) is shown to result in the "purification" of another quantum system in interaction with the former. Even though the measurements are performed on the former system, their effect drives the latter into a pure state, irrespectively of its initial (mixed) state, provided certain conditions are satisfied.
