Quantinuum Inc.
A maker of quantum computers, Quantinuum builds both the machines and the software that run on them. Its trapped-ion systems, the H-Series, tackle complex problems in fields like drug discovery, materials science, and secure communications. The company formed in 2021 when Honeywell's quantum hardware division merged with the U.K. software startup Cambridge Quantum, and its name blends "quantum" with "continuum." Its machines literally shuttle individual atomic ions around the chip like tiny taxis, and they've even demonstrated quantum teleportation.
