3 Millionaire-Maker Quantum Computing Stocks

The article highlights three quantum computing stocks as potential high-risk, high-reward investments: IonQ, Quantinuum, and Rigetti Computing. IonQ leads with 99.99% two-qubit gate fidelity and plans to release a 256-qubit system next year. Quantinuum recently achieved 99.9995% logical fidelity and aims for fault-tolerant quantum computing by 2029. Rigetti takes a different approach with superconducting technology, prioritizing speed over current accuracy. All three are early-stage companies with no guarantee of profitability, requiring continued external funding until achieving commercial viability.

Where Will Rigetti Computing Stock Be in 3 Years?

Rigetti Computing stock has declined 48% in 2026 amid sector-wide quantum computing selloffs. The company's 108-qubit system achieves 99.1% fidelity, falling short of its 99.9% three-year target. With a letter of intent for up to $100M in government funding and revenue growth to $5.1M in Q2, investors should treat Rigetti as part of a diversified quantum computing portfolio rather than a standalone bet, given execution risks on its 2029 milestones.

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.

Is Rigetti Computing a Top Quantum Computing Stock to Buy Now?

Rigetti Computing faces significant challenges in the quantum computing race, particularly with accuracy issues. While the company secured a $100 million government contract under the CHIPS Act, its 108-qubit system has only 99.1% accuracy compared to competitor IonQ's expected 99.99% accuracy in 2027. This performance gap has led clients to favor IonQ, as evidenced by IonQ's $80 million Q2 revenue versus Rigetti's $5 million, prompting analysts to recommend IonQ over Rigetti.
