This builds on Rigetti’s existing strategic collaboration with HPE to commercialize quantum-enabled high-performance computing systems.  BERKELEY, Calif., July 27, 2026 (GLOBE NEWSWIRE) -- Rigetti Computing, Inc. (Nasdaq: RGTI) (“Rigetti” or the “Company”), a pioneer in full-stack quantum-classical computing, today announced that it will partner with HPE and Pittsburgh Supercomputing Center (“PSC”) to build the TangleLab supercomputing testbed. The PSC-based testbed, which is being funded by a $5 million National Science Foundation (“NSF”) grant, will feature a supercomputer powered by a 9-qubit Novera™ quantum computing system integrated with a classical high-performance computing (“HPC”) system. This project builds on Rigetti and HPE’s collaboration to commercialize quantum-enabled high-performance computing systems. Together, Rigetti and HPE are aiming to advance hybrid quantum-classical workflows for research institutions, public sector organizations, and enterprises exploring the future of HPC. “We are excited to have a Novera at the core of TangleLab, which will provide researchers and educators access to a state-of-the-art hybrid quantum-classical computer to push the boundaries of quantum computing innovation and discovery. This system will benefit from the fast gate speeds that are intrinsic to superconducting quantum systems, a critical metric for high-performance hybrid quantum computing environments,” said Dr. Subodh Kulkarni, Rigetti CEO. “Moreover, by collaborating with HPE, the global leader in HPC, we are in a strong position to deliver world-leading hybrid computing solutions -- starting with TangleLab.” “Realizing the potential of quantum computing will depend on how effectively quantum processors integrate with high-performance computing, AI, and advanced networking,” said Masoud Mohseni, Senior Distinguished Technologist and Director of HPE Quantum at HPE Labs. “HPE’s role in TangleLab is to bring those technologies together into a unified hybrid environment, enabling researchers to develop, benchmark, and optimize quantum-classical workflows while gaining critical insight into how future quantum-HPC-AI systems will operate at scale.” PSC will allocate time on the computer using a flexible competitive proposal process. The goal will be to allow individual researchers to use the system in a dedicated manner when needed, while educators will also have real-time access when teaching classes and workshops. To help users of TangleLab come up to speed regardless of their level of experience with quantum computing, PSC will offer onboarding activities, training, and in-depth research consulting. Construction of TangleLab is expected to begin at PSC’s new data center on September 1, 2026, with full operations expected in 2027. TangleLab is funded by the NSF Advanced Computing Systems &amp; Services program under award # 2537076. The system directly addresses national investment and action priorities for Fiscal Year 2027, listed in memorandum M-25-34/NSTM-2 from the Office of Science and Technology Policy, including enabling advancement in quantum information science and artificial intelligence. About Rigetti Rigetti is a pioneer in full-stack quantum computing. Rigetti quantum computers are based on superconducting qubits, which are widely believed to be the leading qubit modality given their maturity, clear path to scaling, and fast gate speeds. Rigetti quantum computing systems achieve gate speeds of 50-70 nanoseconds, which is about 10,000 times faster than trapped-ion systems and 100x faster than neutral-atom systems. Rigetti sells on-premises 9-qubit to 108-qubit quantum computing systems, which support national laboratories and quantum computing centers. Rigetti’s Cepheus 36-qubit to 108-qubit systems are based on the Company’s proprietary chiplet-based technology and include the Company’s control electronics. Rigetti’s 9-qubit Novera QPU supports a broader R&amp;D community with a high-performance, on-premises QPU designed to plug into a customer’s existing cryogenic and control systems. The Company operates quantum computers over the cloud through its Rigetti Quantum Cloud Services (QCS) platform, enabling global enterprise, government, and research clients to pursue R&amp;D. The Company’s proprietary quantum-classical infrastructure provides high-performance integration with public and private clouds for practical quantum computing. Rigetti developed the industry’s first multi-chip quantum processor for scalable quantum computing systems. Leveraging this proprietary technology, Rigetti deployed the industry’s largest multi-chip quantum computer in 2026 with Cepheus-1-108Q, based on twelve 9-qubit chiplets tiled together. The Company designs and manufactures its chips in-house at Fab-1, the industry’s first dedicated and integrated quantum device manufacturing facility.
