Quantum thesis
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.

IBM runs the most mature commercial quantum program of any public company. IBM Quantum operates a fleet of superconducting processors over the cloud, publishes a detailed hardware roadmap, and ships Qiskit, the most widely used open-source quantum software stack. Quantum is a tiny share of IBM revenue, but no other diversified bet has more direct quantum exposure or a longer track record.
