This work targets topological quantum computing: a GPU-accelerated pipeline compiles braid sequences for two-qubit Fibonacci-anyon gates, reporting leakage and error near 10^-10 at braid length 69. The results are so far theoretical and computational, and the article does not show a physical implementation. Readers should watch whether the method carries over to experimental topological platforms, where the gap between simulated and realised fidelity is usually large.
Researchers Find Fibonacci Anyon Gate with Near-Zero Error
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.
A computational pipeline using graphics processing units compiles braids representing two-qubit gates based on Fibonacci anyons; this sharply reduced unwanted signal leakage to one ten billionth, with error rates also around that level at braid length sixty-nine. The advancement enables more complex quantum operations than previously possible due to improved control over these delicate systems.…
