Rigetti Computing Will Deploy Quantum Computer With Over 1,000 Qubits in UK
Summarize this article with:
Rigetti Computing will invest $100 million in the United Kingdom to deploy a quantum computer exceeding 1,000 qubits within the next three to four years, marking the company’s first substantial investment outside of the United States. This move follows the UK government’s commitment of up to £2 billion to establish the nation as a global leader in quantum computing and builds upon Rigetti’s existing presence, including a 36-qubit system at the National Quantum Computing Centre. Subodh Kulkarni of Rigetti stated that their presence in the UK has been marked by fruitful collaboration across industry, government, and academia, highlighting the strength of the UK’s quantum ecosystem. This investment reflects a shared ambition to advance quantum technology, with the goal of achieving a quantum system capable of one trillion quantum operations by 2035. Rigetti’s $100 Million UK Investment for Quantum Expansion The investment is not solely financial; Rigetti highlights a pre-existing collaborative environment as a key driver. Kulkarni further noted that the UK government’s dedication to advancing quantum computing technology is evident across the UK’s entire quantum ecosystem, positioning the nation as an ideal location for expansion. UK Technology Secretary Liz Kendall affirmed the alignment of goals, stating that Rigetti shares their ambition to harness quantum technology to improve lives, livelihoods, and public services, and this $100 million investment is a strong and immediate vote of confidence in their approach. She also highlighted the anticipated impact of the government’s £2 billion plan, noting it is already having a positive impact on jobs and investment, suggesting a synergistic effect between public and private sector initiatives. 1,000+ Qubit System Deployment Planned Within 3-4 Years This expansion is not simply about increasing qubit count, but also about establishing a robust, scalable platform for practical quantum computation. Rigetti explains that this phased approach allows for rapid learning and refinement of the technology. Current Rigetti systems, utilizing superconducting qubits, already demonstrate gate speeds of 50-70 nanoseconds, a substantial advantage over alternative qubit modalities like ion traps and neutral atoms, which are reportedly around 1,000 times slower. The company manufactures its chips in-house at Fab-1, described as the industry’s first dedicated and integrated quantum device manufacturing facility, and offers systems ranging from 9 to 108 qubits. Superconducting Qubits & Chiplet Technology for Scalability Rigetti Computing is focusing on superconducting qubit technology, and a key element of their strategy involves an innovative approach to scaling: chiplets. The company is focused on building larger, more stable quantum processors through modularity, a technique already proving successful with their Cepheus systems. In 2025, Rigetti deployed the industry’s largest multi-chip quantum computer, Cepheus-1-36Q, constructed by tiling together four 9-qubit chiplets; this demonstrated the viability of their technology for creating more complex systems. This approach contrasts with monolithic designs, where all qubits reside on a single, large chip, which present significant manufacturing challenges as complexity increases. The company’s in-house chip fabrication facility, Fab-1, underscores its commitment to vertically integrated manufacturing and control over the entire quantum computing stack, ultimately aiming to translate research into tangible, real-world applications.
