编织Majorana零模是实现拓扑量子计算的关键步骤。然而，编织操作的复杂性阻碍了其实验实现。在此，我们提出了一个由MZM和量子点态组成的实验装置，它可以大大简化MZM的编织协议。这样的编织方案，对应于参数空间中的特定闭环，是相当通用的，并且可以在各种平台中实现。此外，编织结果可以通过电流来测量和表征，为检测MZM的非阿贝尔统计特性提供了一种简单而新颖的方法。
Braiding Majorana zero modes (MZMs) is the key procedure toward topological quantum computation. However, the complexity of the braiding manipulation hinders its experimental realization. Here we propose an experimental setup consisting of MZMs and a quantum dot state which can substantially simplify the braiding protocol of MZMs. Such braiding scheme, corresponding to a specific closed loop in the parameter space, is quite universal and can be realized in various platforms. Moreover, the braiding results can be measured and manifested through electric current, providing a simple and novel way to detect the non-Abelian statistics of MZMs.
