Anyons are fractionally charged quasiparticles of the quantum Hall effect, and could one day power topological quantum computers. Trapping and measuring anyons remains difficult, but quasiparticle charges have now been measured using a gate-defined antidot in bilayer graphene. For hole-conjugate states, the parity of downstream integer edge modes sets the observed charge.
