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.

NVIDIA does not build quantum computers but supplies the GPU-based simulation and hybrid-classical infrastructure used by nearly every serious quantum hardware team. CUDA-Q is its platform for hybrid quantum-classical workloads and increasingly co-located GPU+QPU systems. Treat NVDA as a picks-and-shovels exposure rather than a direct quantum bet.
