我们介绍了一个新的图形框架设计量子纠错码的经典原则的基础上。与以前的方法相比，这种图形语言的一个关键特征是它与经典信息论和机器学习中的因子图或图形模型密切相关。它使我们能够制定最近推出的“相干奇偶校验”量子纠错码的描述完全在经典信息论的语言。这使得我们的构建不需要量子纠错甚至量子力学的背景。更重要的是，这允许一种协作的相互作用，人们可以从经典代码中设计新的量子纠错码。
We introduce a new graphical framework for designing quantum error correction codes based on classical principles. A key feature of this graphical language, over previous approaches, is that it is closely related to that of factor graphs or graphical models in classical information theory and machine learning. It enables us to formulate the description of the recently-introduced ‘coherent parity check’ quantum error correction codes entirely within the language of classical information theory. This makes our construction accessible without requiring background in quantum error correction or even quantum mechanics in general. More importantly, this allows for a collaborative interplay where one can design new quantum error correction codes derived from classical codes.
