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.

Rigetti is a pure-play superconducting quantum computing company that designs its own multi-chip processors and operates a quantum cloud platform. The thesis rests on superconducting qubits being the same architecture used by IBM and Google, with Rigetti positioned as the smallest-cap way to own that approach. Execution risk is high, revenue is research-grade, and the share count has expanded materially.
