提出了一种使用同源乘积码来实现通用容错逻辑门集的方法。特别是,它表明人们可以在给定逻辑状态的不同编码表示之间进行容错映射,从而能够应用属于底层量子代码的不同类别的横向门。这允许规避与通用横向门集有关的不通过结果,并提供容错计算的通用方案,同时保持代码的稳定器生成器稀疏。
A method for the implementation of a universal set of fault-tolerant logical gates is presented using homological product codes. In particular, it is shown that one can fault-tolerantly map between different encoded representations of a given logical state, enabling the application of different classes of transversal gates belonging to the underlying quantum codes. This allows for the circumvention of no-go results pertaining to universal sets of transversal gates and provides a general scheme for fault-tolerant computation while keeping the stabilizer generators of the code sparse.
