Novel approach to quantum error correction portends a scalable future for quantum computing

A University of Sydney quantum physicist has developed a new approach to quantum error correction that could significantly reduce the number of physical qubits required to build large-scale, fault-tolerant quantum computers. The study, co-authored by Dr. Dominic Williamson from the School of Physics, is titled “Low-overhead fault-tolerant quantum computation by gauging logical operators” and published in Nature Physics.
