The global race to make a practical quantum computer just took a big leap forward

By Animesh Datta, Professor of Quantum Information Science, University of Warwick

In the global race to build bigger and better quantum computers, researchers have taken a step forward. A new machine called Helios is a radically different system compared to other quantum computers.

Quantum computers harness the power of quantum mechanics, the laws that govern how physics operates at atomic and sub-atomic scales. Among various designs for such machines, Helios is a trapped-ion quantum computer, which means it uses charged atoms suspended in free space using electromagnetic fields.…
