Quantum Computers and Anyons

In the April 10 2020 issue of the Journal Science the best evidence yet for the existence of a quasiparticle called a "Anyon" is presented. Anyon's are important because when 2 Anyon's loop around each other their quantum state is altered and so that brading can be used to encode information. Such
