Anyons are quasiparticles that, unlike fermions and bosons, show fractional statistics when two of them are exchanged. Here, we report the experimental observation of anyonic braiding statistics for the ν = 1/3 fractional quantum Hall state by using an electronic Fabry–Perot interferometer. Strong Aharonov–Bohm interference of the edge mode is punctuated by discrete phase slips that indicate an anyonic phase θ_anyon = 2π/3. Our results are consistent with a recent theory that describes an interferometer operated in a regime in which device charging energy is small compared to the energy of formation of charged quasiparticles, which indicates that we have observed anyonic braiding.

Anyon是准粒子，与费米子和玻色子不同，当它们中的两个交换时，它们显示出分数统计。在这里，我们报告使用电子法布里-珀罗干涉仪对ν = 1/3分数量子霍耳状态的非离子编织统计进行的实验观察。边缘模式的强阿哈罗诺夫博姆干扰由离散相卡瓦，其指示一个anyonic相穿插θ_任意子=2π/ 3。我们的结果与最近的理论相一致，该理论描述了一种干涉仪，该干涉仪的工作状态是器件的带电能量比带电的准粒子的形成能量小，这表明我们已经观察到非离子编织。
