Quantum thesis
Honeywell spun its quantum hardware group into Quantinuum, a privately held trapped-ion company in which Honeywell holds a majority stake. Buying HON is the only public-market way to own Quantinuum equity, but quantum is a small fraction of Honeywell's diversified industrial revenue, so the exposure is highly diluted.

IonQ is the largest pure-play public bet on trapped-ion quantum computing. The company builds quantum processors that manipulate individual ytterbium ions with lasers, an approach prized for high gate fidelity and long coherence times. Revenue is still small and tied to government and cloud-marketplace contracts, but IonQ has become the most-traded ticker whenever quantum-computing headlines move retail flows.
