Rigetti Computing (RGTI) stock has dropped over 60% from its 2025 high but is still an up-and-coming quantum computing stock. The company competes with tech giants like Google and IBM in the quantum computing industry. Rigetti aims to optimize its quantum computers in terms of speed, accuracy, and scale.

Rigetti’s 108-qubit quantum system boasts gate speeds of 50-70 nanoseconds, making it one of the fastest systems available. However, its accuracy, measured by two-qubit gate fidelity, is only 99%, with smaller systems performing slightly better. Rival IonQ boasts higher fidelity rates but at slower speeds.

CEO Dr. Subodh Kulkarni aims to achieve 99.5% median two-qubit gate fidelity in Rigetti’s Cepheus-1-108Q system. For quantum computers to be commercially viable, they need at least 1 million physical qubits and close to 99.99999% fidelity. Rigetti plans to have 1,000 qubits by 2027, but the industry is still far from mainstream adoption.

Investing in Rigetti comes with high risk, as the company is speculative and faces tough competition. The quantum computing market is projected to reach $72 billion by 2030. Investors may consider diversifying their investments in quantum computing companies or a quantum computing ETF for better odds of success.
