摘要

我们证明了多维芝诺效应与非完整控制相结合，可以通过类似于经典随机编码的方法有效地保护量子系统免受退相干的影响。该方法适用于任意误差诱导哈密顿量和一般量子系统。对于大维增长，量子编码接近汉明上界。用一台七量子位玩具计算机验证了该方法的适用性。

Coherence protection by random coding.

We show that the multidimensional Zeno effect combined with non-holonomic control allows one to efficiently protect quantum systems from decoherence by a method similar to classical random coding. The method is applicable to arbitrary error-inducing Hamiltonians and general quantum systems. The quantum encoding approaches the Hamming upper bound for large dimension increases. Applicability of the method is demonstrated with a seven-qubit toy computer.
