Ordinary wires: electrons jostle, lose energy, and heat up: that's resistance. In superconductors, some electrons pair up in sync, like dancers swirling without collisions. But these pairs hide: you can't see them directly, only infer their presence from flawless coordination.

In the new Helios processor, 98 barium ions circle along a closed loop, like horses on a carousel. This architecture allows any ion to exchange data with any other, making the system flexible and powerful. Laser pulses, like a conductor's baton, issue commands at the speed of light.
