The company's hardware business centers on trapped-ion quantum computers — machines that use electrically charged atoms held in place by electromagnetic fields as the basic units of computation, known as qubits. Trapped-ion systems are considered among the most accurate available, and Quantinuum markets its hardware under the H-Series name, with later generations sold under names including Helios. Its software and applications arm, inherited from Cambridge Quantum, covers quantum chemistry, cybersecurity, and machine learning tools designed to run on quantum hardware.
