Anharmonicity and Charge-Noise Sensitivity of Fraunhofer Qubit

This paper presents a theoretical framework for a flux-tunable "Fraunhofer qubit" based on wide ballistic Josephson junctions, demonstrating that magnetic flux can transform the potential landscape to significantly enhance anharmonicity while maintaining charge-noise protection, thereby offering an optimized operating point for hybrid superconducting circuits.

Pressure-Induced Metal-Insulator and Paramagnet-Altermagnet Transitions in Rutile OsO2 Single Crystals

By synthesizing high-quality rutile OsO2 single crystals, researchers discovered that while the material is initially a paramagnetic metal, applying high pressure (44 GPa) induces a metal-insulator transition and drives a phase change into an altermagnetic state, demonstrating that external pressure can effectively tune its magnetic ground state.
