The development of fault-tolerant circuits for quantum technology has advanced significantly, according to scientists and engineers. In a pair of articles, they claim to have found signs of” fractional quantum anomalous Hall” ( FQAH ) states in experiments with semiconductor material flakes, each of which was only one layer of atoms thick. Because FQAH states can host anyons— surprising” quasiparticles” that have only a fraction of an electron’s charge— their discoveries represent the first and most promising step in the development of some kind of fault-tolerant qubit. What are referred to as” topologically protected” qubits, which are stable against any minor local perturbations, can be created using some types of anyons.
