Sydney and IBM Researchers Leverage Gauge Theory for Low-Overhead Fault Tolerance

Dr. Dominic Williamson (University of Sydney) and Theodore J. Yoder (IBM) have introduced a “gauging” procedure for fault-tolerant logical measurement in quantum error-correcting codes. Published in Nature Physics, the research was developed during Williamson’s industrial placement at IBM. The methodology addresses a critical bottleneck in Quantum Low-Density Parity-Check (qLDPC) codes: how to perform logical processing […]
