Abstract
We report experimental realization of a quasiparticle interferometer where the entire system is in $1/3$ primary fractional quantum Hall state. The interferometer consists of chiral edge channels coupled by quantum-coherent tunneling in two constrictions, thus enclosing an Aharonov-Bohm area. We observe magnetic flux and charge periods $h/e$ and $e/3$, equivalent to the creation of one quasielectron in the island. Quantum theory predicts a $3h/e$ flux period for charge $e/3$, integer statistics particles. Thus, the observed periods demonstrate the anyonic braiding statistics of Laughlin quasiparticles.
