A quantum gate with both leakage and error rates around one ten-billionth has been demonstrated, a feat previously beyond reach. Optimised algorithms combined with GPU acceleration have achieved this fidelity at braid length 69 using Fibonacci anyons, surpassing previous methods reliant on random searches. This advance opens new avenues towards building more dependable topological qubits by directly compiling high-fidelity gates.
