Austin Team Cuts Quantum Error Rates by Nineteen Per Cent

Optimising Clifford deformation, a technique to reduce errors in quantum systems without extra hardware, has been hampered by intensive computational demands; global searches proved impractical and simpler methods often performed poorly. A new compiler named Chameleon sharply reduces logical error rates with substantially lower computation time, achieving maximum reductions of nineteen per cent relative to existing approaches for surface codes. Won Joon Yun Quantum AI and colleagues have created Chameleon, a system that improves quantum computer reliability without altering their physical components. By optimising information processing using Clifford deformation, Chameleon lowers error rates by up to nineteen per cent…
