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 .
The main problem of quantum computing is
errors . The more complex the task, the higher the chance of failure.
Helios breaks this pattern: its operations are 99.992% accurate — roughly
one error per 12,500 steps . This is a record for systems of this size.
Meanwhile, the temperature in the trap is close to absolute zero — colder than interstellar space . Laser measurements check the state of each ion. Such reliability paves the way for computations unimaginable for classical supercomputers . The idea of a quantum computer was proposed by Richard Feynman , and the ion trap technology was developed by David Wineland .
Barium-137 was not chosen by chance: its energy levels are so convenient that a laser tunes them like a remote flips through TV channels.
Such a machine resembles the quantum computer from Arthur C. Clarke's novel, capable of modeling consciousness.
