Austin Team Cuts Quantum Error Rates by Nineteen Per Cent
A team at the University of Texas at Austin reported an optimisation method for the BB72 quantum error-correcting code that reduces quantum error rates by 19 per cent. The code optimisation previously took 1.2 days of computation; the new approach completes in 3.1 minutes.
If this optimisation technique transfers to other quantum error-correcting codes and hardware platforms, it could enable near-real-time re-tuning of code parameters during routine device calibration, adapting to measured noise drift.
