Scientists at Quantinuum have unveiled the world's most powerful quantum computer. The team claims the new system is capable of solving a problem that a supercomputer could handle only if it consumed more power than the total wattage of a quasar — one of the brightest objects in the universe.
At the heart of the new machine, known as Helios, is a quantum processing unit (QPU) with 98 physical qubits made of barium ions. These qubits are arranged in a "junction ion trap" formation — a small, ring-like structure that forms a crossover junction at the base, before extending into two parallel rods.
