动力学定域、测量和量子计算

Dynamical localization, measurements and quantum computing

M. Terraneo, D. L. Shepelyansky

摘要:

在量子计算机上模拟了被踢旋转体模型,数值研究了测量对动力学局域化的影响。与以前的研究相反,这些研究表明,测量会引起扩散的概率扩展,我们的结果表明,重复的单量子比特测量可以保持本地化。我们检测到从本地化到一个离域相位的过渡,这取决于系统参数和测量的量子位的选择。

英文摘要:

We study numerically the effects of measurements on dynamical localization in the kicked rotator model simulated on a quantum computer. Contrary to the previous studies, which showed that measurements induce a diffusive probability spreading, our results demonstrate that localization can be preserved for repeated single-qubit measurements. We detect a transition from a localized to a delocalized phase, depending on the system parameters and on the choice of the measured qubit.
