We report localization of fractional quantum Hall (QH) quasiparticles on graphene antidots. By studying coherent tunneling through the localized QH edge modes on the antidot, we measured the QH quasiparticle charges to be approximately $\pm e/3$ at fractional fillings of $\nu =\pm 1/3$. The Dirac spectrum in graphene allows large energy scales and robust quasiparticle localization against thermal excitation. The capability of localizing fractional quasiparticles on QH antidots brings promising opportunities for realizing anyon braiding and novel quantum electronics.

在石墨烯量子霍尔解毒剂上局部化分数拟粒子

我们报告分数量子霍尔（QH）准粒子在石墨烯解毒剂上的定位。通过研究解毒剂上局部QH边缘模式的相干隧穿，我们测得QH准粒子电荷约为$\pm Ë/3$ 在部分填充 $\nu =\pm \mathrm{1个}/3$。石墨烯中的狄拉克光谱允许较大的能量规模和针对热激发的鲁棒准粒子定位。在QH解毒剂上定位分数类准粒子的能力为实现Anyon编织和新型量子电子学带来了广阔的机遇。
