A new ion-based quantum computer makes error correction simpler

Quantinuum has introduced Helios, a third-generation ion-based quantum computer with enhanced computing power and error correction capabilities. The machine, using barium ions as qubits, is designed to be easier to scale up compared to quantum computers using superconducting circuits. Helios encodes information in quantum states, allowing for superpositions of 0s and 1s. The computer's design enables efficient error correction with fewer physical qubits, showcasing precision and low error rates. Quantinuum plans to further develop its quantum computing technology with future generations like Sol and Apollo, aiming for thousands of physical qubits and full fault tolerance by 2029.
