Rigetti Computing
Rigetti Computing (NASDAQ: RGTI) is a US quantum hardware company developing superconducting qubit processors. It competes in the quantum-computing hardware market against ionq, google-quantum-ai, Quantinuum, Microsoft, and others.
Recent Performance
- 99.9% 2-qubit-gate-fidelity — achieved on a small R&D prototype (as of article date)
- 99% fidelity — its 108-qubit production system
- Market cap < $5 billion
Competitive Position
ionq surpassed 99.99% fidelity in October 2025, leaving Rigetti behind despite its prototype record. Rigetti’s production system scaling (99% vs 99.9% prototype) signals underlying engineering challenges.
Motley Fool analyst Keithen Drury does not recommend Rigetti stock, preferring companies with differentiated technology (IonQ) or large-incumbent resources (Microsoft, Google). An alternative is a quantum computing ETF for diversified exposure.
