Rigetti Reports Improved Fidelity on 108-Qubit System, Secures $100 Million CHIPS Act Funding
Rigetti Computing, Inc. has announced its financial results for the third quarter ended September 30, 2026, alongside significant technological milestones. The company reported achieving 99.5% median two-qubit fidelity on its 108-qubit Cepheus-1-108Q system, validating its chiplet-based architecture for scaling superconducting quantum computers. This system is composed of twelve interconnected 9-qubit chiplets. Rigetti also secured a definitive agreement with the U.S. Department of Commerce for up to $100 million in funding under the CHIPS Research and Development Office Broad Agency Announcement, part of the CHIPS Act. This funding will support three key research and development programs: miniaturized readout electronics, expanded cryogenic capacity through a new cryostat architecture, and fabrication capabilities for high-connectivity chip architectures. As a condition of the award, the Department of Commerce received a minority, non-controlling equity stake in Rigetti.
