A University of Sydney quantum physicist has developed a new approach to quantum error correction - using lattice gauge theory - that could significantly reduce the number of physical qubits required to build large-scale, fault-tolerant quantum computers.

Many people have likely found themselves watching oddly satisfying videos of random objects being squashed by a powerful hydraulic press, but rarely people consider why things squash the way they do.

A joint research team between the Center for Quantum Information and Quantum Biology (QIQB) at The University of Osaka and Fixstars Corporation has demonstrated one of the world's largest classical simulations of iterative quantum phase estimation (IQPE) quantum circuits for quantum chemistry on up to 1,024 GPUs, surpassing the previous 40-qubit limit. The result expands the scale of molecular systems available for the development and validation of quantum algorithms for future fault-tolerant quantum computers, supporting progress toward industrial applications in drug discovery and materials development.
