如何纠正小的量子错误

How to correct small quantum errors

M. Keyl, R. F. Werner

摘要:

量子纠错理论是量子信息处理的基石。这表明量子数据可以免受退相干效应的影响,否则许多新的量子应用实际上是不可能的。在本文中,我们给出了一个自我包含的介绍这个理论和密切相关的概念,量子信道的能力。我们表明,特别是,它是可能的(使用适当的纠错方案)发送一个非零量的量子数据不受干扰(在一定的渐近意义上)通过一个嘈杂的量子信道T,提供由T产生的错误是足够小的。

英文摘要:

The theory of quantum error correction is a cornerstone of quantum information processing. It shows that quantum data can be protected against decoherence effects, which otherwise would render many of the new quantum applications practically impossible. In this paper we give a self contained introduction to this theory and to the closely related concept of quantum channel capacities. We show, in particular, that it is possible (using appropriate error correcting schemes) to send a non-vanishing amount of quantum data undisturbed (in a certain asymptotic sense) through a noisy quantum channel T, provided the errors produced by T are small enough.
