Quantum-computing company Rigetti (Nasdaq: RGTI) reported 99.5% median two-qubit fidelity on its 108-qubit system, which uses a chiplet-based architecture.

Rigetti Computing reported 99.5% median two-qubit fidelity on its 108-qubit system. The result concerns its chiplet-based quantum processing unit (QPU) architecture, not a classical GPU or CPU system.

The metric is specifically a median two-qubit fidelity, rather than a stated minimum across every qubit pair or an end-to-end application success rate. Rigetti characterized the result as further validation of its chiplet architecture, but the supplied excerpt does not include the measurement protocol or distribution of results.

The update accompanied financial results for the third quarter ended September 30, 2026, announced on November 11. Although the source identifies the company as Nasdaq: RGTI, the excerpt contains no revenue, loss, cash, financing, or capital-expenditure figures to analyze.
