In 2D quantum systems, particles called anyons obey statistics intermediate between bosons and fermions. When one anyon winds around another, the quantum state acquires a phase eiθ with θ anywhere between 0 (bosons) and π (fermions). For non-Abelian anyons, the operation is a unitary matrix — braiding implements a quantum gate.
The visualization shows anyon world-lines sweeping through time. The key insight: quantum information encoded in the topological winding number is immune to local perturbations, making it naturally fault-tolerant. Fibonacci anyons and Majorana zero modes are leading physical candidates.
