  "account": "Four independent research teams have reported significant advancements in the design of quantum devices using 'spin qubits' to encode information. Spin qubits are created by precisely carving patterns into semiconductor wafers, forming wells that can hold a single electron. Previously, systems using spin qubits were considered less promising due to their small size and high error rates. However, the new systems range from 5 to 18 qubits and have managed to reduce the error rate to less than 0.01%, a major breakthrough.",
  "summary": "Nature, Published online: 30 July 2026; doi:10.1038/d41586-026-02420-9 The tool can add, remove or swap protein subunits using similar steps to natural evolution. Plus, spin qubits are back in the quantum race and the drugs that could prevent long COVID.",
