Quantinuum, an industry-leading quantum computer company, has made available Helios — its latest quantum computer system, featuring 98 fully connected physical qubits. The new system is labelled as the world’s most accurate general-purpose commercial quantum computer. It is intended to advance commercial applications of quantum computing in industries such as drug discovery, finance, and the development of new materials.
They explain that Helios is Quantinuum’s third-generation quantum technology, which has moved from using ytterbium ions to barium ions for Qubits. This is significant because visible-spectrum lasers (due to being cheaper, easier to scale commercially, and more reliable) can be manipulated by this switchover. Finally, a barium qubit enables the system to sense and correct errors at the atomic level, thereby improving computational capability. Helios delivers unprecedented accuracy, with single-qubit gate fidelity of 99.9975% and two-qubit gate fidelity of 99.921% across all qubits.
It was Quantinuum’s Helios, which utilizes its QCCD (quantum charge-coupled device) architecture to offer full all-to-all connectivity between qubits. As a result, any qubit can be entangled with any other to support algorithms and error correction codes that are not feasible in the fixed-qubit architecture of superconducting quantum computers. The system also provides a real-time control engine, which enables quantum programs to act in a feedback-driven fashion while executing and interleaving classical GPU-accelerated computations with quantum ones within the same program.
Helios features advanced logical qubit capabilities, including 94 globally entangled logical qubits with error detection and 48 fully error-corrected logical qubits, with 99.99% state preparation and measurement fidelity. Helios is ahead in the race for practical quantum advantage because it has this level of error correction and qubit quality.
Some of the first major companies to utilize Helios are Amgen, BMW Group, JPMorgan Chase, and SoftBank. They are using the quantum computer for research in biologics, sustainable mobility materials, advanced financial analytics, and organic materials. Quantinuum has also partnered with Singapore’s National Quantum Office and established a research, development, and operations center there to support local deployment.
Quantinuum intends to continue scaling up its quantum systems, with a next-generation computer called Sol due in 2027 that will feature 192 physical qubits. Apollo is expected to follow three years later, offering thousands of physical qubits and full fault tolerance. The release of Helios is an important step on this path to universal, fault-tolerant quantum computing at scale.”
Overall, the Helios quantum computer from Quantinuum is a cutting-edge platform that combines high qubit connectivity, low error rates, real-time quantum-classical hybrid computing, and enterprise readiness. This makes it easier for generative quantum AI, materials science, and finance to move forward.
