论文摘要
自1977年Misra和Sudarshan发现以来，量子Zeno效应（QZE）一直是量子力学中最有趣的现象之一[J.数学。物理。 \ textbf {18}，756（1977）]。有许多尝试实现相同的尝试。在这里，我们介绍了IBM量子体验平台上QZE的第一个模拟。我们模拟了一个两级系统，以用于Rabi驱动的振荡，然后使用量子门中间重复测量来干扰时间演变，以增加初始状态下Qubit的生存概率。这些电路与添加的中间测量结果一起设计并在IBM量子模拟器上执行，并且结果证明结果与预测一致。中等测量的数量的生存率增加表明了QZE。此外，还提供了获得的结果的一些替代解释，这导致了一些歧义，从而为观察到的结果提供了确切的推理。
Quantum Zeno Effect (QZE) has been one of the most interesting phenomena in quantum mechanics ever since its discovery in 1977 by Misra and Sudarshan [J. Math. Phys. \textbf{18}, 756 (1977)]. There have been many attempts for experimental realization of the same. Here, we present the first ever simulation of QZE on IBM quantum experience platform. We simulate a two-level system for Rabi-driven oscillation and then disturb the time evolution by intermediate repetitive measurements using quantum gates to increase the survival probability of the qubit in the initial state. The circuits are designed along with the added intermediate measurements and executed on IBM quantum simulator, and the outcomes are shown to be consistent with the predictions. The increasing survival probability with the number of intermediate measurements demonstrates QZE. Furthermore, some alternative explanations for the obtained results are provided which leads to some ambiguity in giving the exact reasoning for the observed outcomes.
