论文摘要
我们通过使用菱形瓷砖利用平面镶嵌来构建双重表面代码。使用n个数据量位，我们能够至少编码N/3逻辑Qubits或量子记忆。通过适当的瓷砖布置，该代码实现了更大的距离，从而导致了明显的错误校正功能。我们证明了在存在外部噪声的情况下获得的逻辑Qubit的鲁棒性。我们认为，此处介绍的代码的最优性将为设计有效的可扩展体系结构设计铺平道路。
We construct a double-toric surface code by exploiting the planar tessellation using a rhombus-shaped tile. With n data qubits, we are able to encode at least n/3 logical qubits or quantum memories. By a suitable arrangement of the tiles, the code achieves larger distances, leading to significant error-correcting capability. We demonstrate the robustness of the logical qubits thus obtained in the presence of external noise. We believe that the optimality of the code presented here will pave the way for design of efficient scalable architectures.
