我们定义并研究了帕拉费米子稳定器代码,这些代码可以被视为基塔耶夫不成对马约拉纳费米子的一维模型的概括。与 Qudit 稳定器代码类似,Parafermion 稳定器代码可以防止作用于一小部分 Parafermion 模式的低权重错误。给出了几个最小的副费米子稳定器代码的示例。建立了一种将 qudit 算子嵌入到 parafermion 算子中的局部性保留嵌入,它允许将已知的 qudit 稳定器代码映射到 parafermion 代码。我们还提出了一种局部二维平费米子结构,它将基塔耶夫环面码的拓扑保护与依赖于宇称守恒的额外保护相结合。
We define and study parafermion stabilizer codes which can be viewed as generalizations of Kitaev's one dimensional model of unpaired Majorana fermions. Parafermion stabilizer codes can protect against low-weight errors acting on a small subset of parafermion modes in analogy to qudit stabilizer codes. Examples of several smallest parafermion stabilizer codes are given. A locality preserving embedding of qudit operators into parafermion operators is established which allows one to map known qudit stabilizer codes to parafermion codes. We also present a local 2D parafermion construction that combines topological protection of Kitaev's toric code with additional protection relying on parity conservation.
