Dr Dominic Williamson of the University of Sydney and Theodore Yoder of IBM published a method in Nature Physics that enables error correction by gauging logical operators. Inspired by lattice gauge theory in particle physics, the approach targets efficient logical operations in qLDPC codes.
The method aims to reduce the number of physical qubits required per logical qubit and has been incorporated into elements of IBM's large-scale quantum roadmap.
