Minimal setup for non-Abelian braiding of Majorana zero modes

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.
