摘要
讨论了量子Zeno 效应中测量的特点, 指出这种测量只是使系统塌缩到原态的一种操作; 通过用控制非门的偶数次操作, 提出了一种理论上更简单、更易实现的二位防错方案。
This paper explains the operation that can make a quantum system collapse into the intial state. The operation can be regarded as measurement in quantum zeno effect. A scheme which is simple and feasible to implement theoretically is proposed by even times of quantum cotrolled NOT opertion.
