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.

D-Wave is the only public pure-play on quantum annealing, an approach optimized for combinatorial-optimization problems rather than universal gate-based computation. The company also offers a gate-model roadmap and a Leap cloud service, but its differentiator is annealing hardware that is already in commercial deployment with customers in logistics and finance.
