Rigetti Demonstrates Industry's Largest Multi-Chip Quantum Computer; Halves Two-Qubit Gate Error Rate

BERKELEY, Calif., July 16, 2025 (GLOBE NEWSWIRE) -- Rigetti Computing, Inc. (Nasdaq: RGTI) (“Rigetti” or the “Company”), a pioneer in full-stack quantum-classical computing, today announced that it has achieved its mid-year performance milestone of 99.5% median two-qubit gate* fidelity on its modular 36-qubit system, a 2x reduction in median two-qubit gate error rate from Rigetti’s previous best results on its 84-qubit single chip Ankaa™-3 system. Composed of four 9-qubit chips (“chiplets”) tiled together, ...
