Fully Operational Rigetti QPU Included in UK’s Recently Opened National Quantum Computer Centre

Rigetti UK Limited, a wholly owned subsidiary of Rigetti Computing, Inc. (Nasdaq: RGTI) (“Rigetti” or the “Company”), a pioneer in full-stack quantum-classical computing, today announced that the UK’s National Quantum Computing Centre (NQCC) officially opened the doors of its landmark facility on Harwell Campus on October 25. The facility will support world-class quantum computing research and provide state-of-the-art laboratories for designing, building, and testing quantum computers. Rigetti’s system located at the NQCC is a fully operational 24-qubit Ankaa™-class quantum computer, featuring tunable couplers and a square lattice for fast gate times, enhanced connectivity, and high fidelity. As part of the implementation, Rigetti will be integrating Riverlane’s technology with the long-term objective of large-scale error correction.

In February 2024, Rigetti was awarded a Small Business Research Initiative (SBRI) grant delivered by Innovate UK and funded by the NQCC to deliver a quantum computing system based on the Company’s Ankaa-class architecture to the new facility. The 24-qubit system will be made available to NQCC researchers for testing, benchmarking, and exploratory applications development.

Rigetti CEO Dr. Subodh Kulkarni and CTO David Rivas attended the official inauguration to celebrate the milestone.

“The NQCC opening is a great occasion for both the UK and Rigetti. We are proud that Rigetti’s on-premises quantum computer is fully operational for the NQCC research team to pursue critical research to advance our understanding of how to use quantum computing to solve real-world problems,” says Rigetti CEO Dr. Subodh Kulkarni.

Cautionary Language Concerning Forward-Looking StatementsCertain statements in this communication may be considered “forward-looking statements” within the meaning of the federal securities laws, including but not limited to, expectations related to the Company’s 24-qubit Ankaa-class system operating at the UK’s National Quantum Computing Centre, including the results of researchers testing, benchmarking and performing exploratory applications development on that system, and the SBRI grant to the Company from Innovate UK. These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by the Company and its management, are inherently uncertain. Factors that may cause actual results to differ materially from current expectations include, but are not limited to: the Company’s ability to achieve milestones, technological advancements, including with respect to its technology roadmap, help unlock quantum computing, and develop practical applications; the ability of the Company to obtain government contracts successfully and in a timely manner and the availability of government funding; the potential of quantum computing; the ability of the Company to expand its QPU sales; the success of the Company’s partnerships and collaborations; the Company’s ability to accelerate its development of multiple generations of quantum processors; the outcome of any legal proceedings that may be instituted against the Company or others; the ability to maintain relationships with customers and suppliers and attract and retain management and key employees; costs related to operating as a public company; changes in applicable laws or regulations; the possibility that the Company may be adversely affected by other economic, business, or competitive factors; the Company’s estimates of expenses and profitability; the evolution of the markets in which the Company competes; the ability of the Company to implement its strategic initiatives, expansion plans and continue to innovate its existing services; the expected use of proceeds from the Company’s past and future financings or other capital; the sufficiency of the Company’s cash resources; unfavorable conditions in the Company’s industry, the global economy or global supply chain, including financial and credit market fluctuations and uncertainty, rising inflation and interest rates, disruptions in banking systems, increased costs, international trade relations, political turmoil, natural catastrophes, warfare (such as the ongoing military conflict between Russia and Ukraine and related sanctions and the state of war between Israel and Hamas and related threat of a larger conflict), and terrorist attacks; and other risks and uncertainties set forth in the section entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, the Company’s Form 10-Q for the three months ended June 30, 2024, and other documents filed by the Company from time to time with the SEC.
