qubits technical

"deploying a quantum computing system in the UK with over 1,000 qubits in the next 3 to 4 years"

Qubits are the basic units of information in quantum computing, similar to how traditional computers use bits. Unlike regular bits that are either 0 or 1, qubits can represent both at the same time, allowing quantum computers to process complex problems much faster. This potential for unprecedented speed and power could transform industries, making qubits a key focus for investors interested in cutting-edge technology.

quantum error correction technical

"part of a consortium focused on advancing quantum error correction capabilities on superconducting quantum computers"

Quantum error correction is a set of methods for detecting and fixing mistakes in quantum computers by encoding fragile quantum information across multiple physical parts, much like using multiple copies or checksums to protect a sensitive digital file. For investors, it matters because reliable error correction is a key technical milestone that determines whether quantum machines can scale from experimental devices to practical tools that could disrupt computing, encryption, drug discovery and other industries.

superconducting quantum computers technical

"advancing quantum error correction capabilities on superconducting quantum computers"

Superconducting quantum computers use circuits kept at extremely low temperatures so tiny electrical currents flow without resistance and store information in quantum states rather than ordinary on/off bits. Because those quantum states can represent many possibilities at once, these machines can solve specific problems far faster than conventional computers; for investors that means potential for outsized returns if the technology unlocks new markets, but also long development timelines and high technical risk.

Rigetti’s investment will go towards deploying a quantum computing system in the UK with over 1,000 qubits in the next 3 to 4 years. This will mark the Company’s first major investment outside of the US.

BERKELEY, Calif., March 25, 2026 (GLOBE NEWSWIRE) -- Rigetti Computing, Inc. (Nasdaq: RGTI) (“Rigetti” or the “Company”), a pioneer in full-stack quantum-classical computing, today announced that it intends to invest up to $100 million in the UK to accelerate quantum computing development, which will be the Company’s first major investment outside of the US. With this investment, the Company plans to deploy a quantum computer with over 1,000 qubits in the next 3 to 4 years. This follows the UK’s recently announced program that will dedicate up to £2 billion of government investment with the aim of establishing the UK as a global leader in quantum computing.

Rigetti CEO Dr. Subodh Kulkarni said:

“Our presence in the UK has been marked by fruitful collaboration across industry, government, and academia. The UK government’s unwavering dedication to advancing quantum computing technology is evident across the UK’s entire quantum ecosystem. The focus on driving end-user engagement and developing on-premises capabilities for meaningful R&D makes the UK an exemplary leader in this revolutionary field.

“We see strong alignment with the UK’s national quantum computing strategy and our own path to fault-tolerant quantum computing. By establishing critical, incremental milestones that work towards a quantum system capable of one trillion quantum operations (“TeraQuOp”) by 2035, we can rapidly learn and innovate throughout the scaling process.

“This investment in the UK’s quantum computing sector is a reflection of the success we’ve already achieved with our UK-based programs and the potential of what lies ahead through the UK’s own investments to drive the industry forward.”

UK Technology Secretary Liz Kendall said:

"Last week, we made a world-first commitment to procure usable large-scale quantum computers by the early 2030s, backed by a £2 billion plan of Government funding, which is already having a positive impact on jobs and investment.

"Rigetti shares our ambition to harness quantum to improve lives, livelihoods, and public services, and this $100 million investment is a strong and immediate vote of confidence in our approach.

"The steps we are taking will deliver world-class infrastructure, access to talent, and a clear pathway which turns ideas from R&D into real-world use, building an environment which will support more companies to scale up and grow on our shores."

This commitment builds on Rigetti’s long-time presence in the UK, which includes the deployment of a 36-qubit quantum system at the National Quantum Computing Centre. The system is part of a consortium focused on advancing quantum error correction capabilities on superconducting quantum computers.

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. Current Rigetti quantum computing systems achieve gate speeds of 50-70ns, which is about 1,000 times faster than other modalities such as ion traps and neutral atoms.

Rigetti sells on-premises 9-qubit to 108-qubit quantum computing systems, supporting 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&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&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 2025 with Cepheus-1-36Q, based on four 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. Learn more at https://www.rigetti.com/.
