Using a quantum computer, researchers simulated a material and for the first time observed how electron pairs form—the ones responsible for superconductivity. Previously they were only detected indirectly. The experiment proves that quantum machines bring us closer to superconductors that work witho

When a quantum computer errs, iceberg codes silently correct the glitches, packing lots of protected data into a small number of real atoms. On a 98-ion processor, a calculation with error correction yielded a more accurate result than without it—proof that reliable quantum machines aren’t just scie
