填充因子 nu=5/2 的量子霍尔态的分数带电准粒子预计遵循非阿贝尔统计。我们证明，可以通过电子马赫-曾德干涉仪中的传输测量来探测它们的统计数据。通过干涉仪的隧道电流表现出对磁通量的特征依赖性和对可由栅极电压控制的隧道振幅的非解析依赖性。
Fractionally charged quasiparticles in the quantum Hall state with a filling factor nu=5/2 are expected to obey non-Abelian statistics. We demonstrate that their statistics can be probed by transport measurements in an electronic Mach-Zehnder interferometer. The tunneling current through the interferometer exhibits a characteristic dependence on the magnetic flux and a nonanalytic dependence on the tunneling amplitudes which can be controlled by gate voltages.
