Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team from the University of Innsbruck, together with a team from RWTH Aachen and Forschungszentrum Jülich, has developed a method and implemented it experimentally for the first time, with which a quantum computer can switch back and forth between two correction codes and thus perform all computing operations protected against errors.

A research team led by Associate Professor Ding PAN from the Department of Physics and the Department of Chemistry at the Hong Kong University of Science and Technology (HKUST), in collaboration with Prof. Yuan Yao from the Department of Mathematics, has made significant discoveries regarding the complex reaction mechanisms of carbon dioxide (CO₂) in supercritical water. These findings are crucial for understanding the molecular mechanisms of CO₂ mineralization and sequestration in nature and engineering, as well as the deep carbon cycle within the Earth's interior. This understanding will help pave the way for new directions in future carbon sequestration technologies. The study was published in the Proceedings of the National Academy of Sciences (PNAS)*.
