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.
