Google Quantum AI Achieves First-Ever Non-Abelian Anyon Braiding

Google Quantum AI has observed non-Abelian anyons for the first time, a breakthrough that could revolutionize quantum computing by making it more robust to noise and leading to topological quantum computation. Non-Abelian anyons retain a sort of memory, and when two of them are exchanged, their world-lines wrap around one another. The resulting knots and braids form the basic operations of a topological quantum computer. The team demonstrated how braiding of non-Abelian anyons might be used in quantum computations and created a well-known quantum entangled state called the Greenberger-Horne-Zeilinger (GHZ) state.
