IonQ vs. Rigetti Computing: Which Is the Better Quantum Computing Stock to Own for the Next 5 Years

IonQ and Rigetti Computing are two pure-play quantum computing companies that have seen stock prices tumble over 30% this year. IonQ uses trapped ion technology and achieved record 99.99% two-qubit gate fidelity with 287% revenue growth, while Rigetti uses superconducting technology with faster gate speeds but lower accuracy. IonQ is recommended as the better buy for the next five years due to lower risk, stronger growth, and a solid $3 billion cash balance.
