Extended Data Fig. 3: Creation and fusion of the quasiparticle excitations.
From: Non-Abelian braiding of Fibonacci anyons with a superconducting processor
a, To create a pair of quasiparticles, we add a short string on the string-net configuration. It can be regarded as connected to the honeycomb lattice with the vacuum string, which can be arbitrarily added and removed. One F-move acting on the type-s string, the type-0 connecting string, and the nearby edge can change the fattened lattice picture6 to the tailed string-net picture. b, To annihilate (fuse) two quasiparticles, we detach the two tails with one F-move to directly connect them. The string connecting these two detached tails indicates the fusion result of these two quasiparticles.
