Should l Buy RGTI?
Rigetti Computing (RGTI) announced the general availability of its 108-qubit quantum computing system, Cepheus-1-108Q, now accessible to customers and partners via the Rigetti Quantum Cloud Services Platform and through Amazon (AMZN) Braket, the quantum computing service by AWS. The company said, "Cepheus-1-108Q is Rigetti's highest qubit-count system to date and the industry's largest modular quantum computing system, based on Rigetti's proprietary chiplet-based architecture. The system comprises twelve interconnected 9-qubit chiplets, tripling the number of qubits and chiplets from Rigetti's previous 36-qubit system, Cepheus-1-36Q. The system is currently performing at a 99.1% median two-qubit gate fidelity with a gate speed of ~60 ns and a 99.9% median single-gate fidelity. Rigetti is releasing Cepheus-1-108Q now in response to growing customer interest, and will continue to improve the system performance throughout 2026 as the Company advances on its roadmap."
