Quantum specialist Quantinuum has placed its newest machine, Helios, on the open market. At the launch the company's public data place Helios at the forefront of both raw strength and experimental honesty, a decisive move forward for the entire field.

Helios holds ninety eight physical qubits, a count that almost reaches twice the number supplied by Quantinuum's earlier platform, the H2. A more vital figure - any pair of qubits inside Helios now shows an overall fidelity of 99.9 %. Measured gate accuracies read 99.9975 % for single qubit gates and 99.921 % for two qubit gates, numbers that reset the bar for reliability in quantum work.

The jump in hardware delivers clear gains in speed. Quantinuum executed a well known benchmark task, once used by Google to claim quantum advantage, that a top tier classical supercomputer would need roughly ten septillion years to finish. Teams are already turning that capability toward large simulations of superconductivity treating Helios as an on chip laboratory to probe matter under conditions that classical machines cannot reach.

Although Helios wields enormous computational range, it draws power comparable to one ordinary server rack. This blend of strength and thrift lets Helios - the generations that will follow - serve as standard instruments for discovery, not only for checking theories but also for discovering ones that no one has yet imagined in the study of materials and beyond.
