AI 中文摘要
我们构造了速率-距离权衡接近CSS GV界的量子CSS码,这些码可通过对数深度和线性数量门的量子电路进行编码。我们的构造深受Brehm和Resch工作的启发,可视为经典重复多重累加码的量子模拟。该编码器具有特别简单的结构,由一个恒定深度的外部量子电路后接若干经典累加和逆累加层组成。
英文摘要
We construct quantum CSS codes with rate-distance tradeoff approaching the CSS GV bound, which can be encoded by a quantum circuit of logarithmic depth and a linear number of gates. Our construction is heavily inspired by a work of Brehm and Resch and can be viewed as a quantum analogue of classical repeat multiple accumulate codes. The encoder has a particularly simple structure, consisting of a single constant depth outer quantum circuit followed by several classical accumulation and inverse-accumulation layers.
