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

A 98-ion processor amplifies weak randomness to near perfection. Quantum entanglement and ultrafast measurements give an attacker just 30 ms—and a safe radius of 4,500 km.

Scientists have created a quantum computer called Helios with 98 ions. It uses a rotating ring so that ions can communicate with each other wirelessly. Calculation errors have become very small. This brings quantum computers closer to solving real-world problems.

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
