Figure 1: The distinct quantum states resulting from particle worldlines in (a) and (b) do not interfere with each other if they follow non-Abelian statistics. (c) Electron micrograph of the interferometric device. (d) Aharonov-Bohm oscillations with sweeping of the gate voltage at filling factor $\nu =5/2$ from $e/4$ and $e/2$ quasiparticles.
