AI总结:

摘要:

我们通过考虑CSS码内部的特定对偶性,将折叠概念从表面码推广到CSS码。具体而言,这提供了一种通用方法,仅使用横向门和量子比特置换,即可在合适的LDPC量子码中实现逻辑操作。为验证我们的方法,我们专门研究了一种名为Bring's code的[[30, 8, 3]]双曲量子码。进一步我们证明,将Bring's code的逻辑子空间限制为4个量子比特时,可在该子空间上获得完整的Clifford群。

英文摘要:

We generalize the concept of folding from surface codes to CSS codes by considering certain dualities within them. In particular, this gives a general method to implement logical operations in suitable LDPC quantum codes using transversal gates and qubit permutations only. To demonstrate our approach, we specifically consider a [[30, 8, 3]] hyperbolic quantum code called Bring's code. Further, we show that by restricting the logical subspace of Bring's code to four qubits, we can obtain the full Clifford group on that subspace.
