Better Quantum Computing Stock to Buy: IonQ vs. Rigetti

IonQ emerges as the superior quantum computing pure-play stock compared to Rigetti Computing, leveraging its trapped-ion technology that achieves 99.99% 2-qubit gate fidelity and generating significantly higher revenue ($65M in Q1 vs. Rigetti's $4.4M). While both companies pursue different quantum computing approaches, IonQ's superior accuracy, greater computational capacity, and stronger market traction position it as the better investment, though diversification through quantum computing ETFs is recommended given sector risks.
