Nu Quantum Raises $60M Series A in Largest Financing Round for Quantum Computer Networking

Nu Quantum, building the quantum networking technology to scale quantum computers, led by Dr. Carmen Palacios-Berraquero, Dr. Claire Le Gall, Ed Wood, Danny Garden, Amii Shepperson, Sam Funnell, and Jonathan Cumming, has secured $60 million in Series A funding round led by National Grid Partners, including participation from Gresham House Ventures and Morpheus Ventures, and continued support from existing investors Amadeus Capital Partners, IQ Capital, Ahren Capital, Cambridge Enterprise Ventures, East Innovate, NSSIF, and Sumitomo (Presidio Ventures).

Nu Quantum has closed the largest Series A for a pure-play quantum networking company in the UK, funding its mission to achieve fault-tolerant quantum computing by interconnecting processors into a distributed system. While quantum computers can tackle problems beyond classical supercomputers, such as atomic-level molecule modeling or large-scale system optimization, scaling to thousands of qubits is essential for real-world utility.

Nu Quantum’s networking approach, the Entanglement Fabric, enables modular, distributed quantum computers. Inspired by networking’s role in classical computing, this architecture supports multiple qubit modalities and lays the foundation for the mass commercialisation of quantum computing in datacenters.

Dr. Carmen Palacios-Berraquero, CEO of Nu Quantum, emphasized the company’s early focus on networked quantum computing to solve industry-scale challenges, praising the team’s culture of innovation and collaboration and calling the investment validation of their vision.

Steve Smith of National Grid Partners highlighted Nu Quantum’s role in bringing quantum computing closer to real-world impact.

Maya Ward of Gresham House Ventures noted the company’s potential to address scaling and fidelity challenges critical for large-scale quantum advantage.

Damien Petty of Morpheus Ventures praised Nu Quantum’s technology and vision for tackling scalability and enabling hybrid interconnectivity.

Dr. Hemant Mardia, Chair of Nu Quantum, compared the company’s photonic networking approach to classical data center networking, noting the Series A funding accelerates the roadmap and global expansion.

Quantum computing requires qubits and high-quality entanglement to perform powerful calculations. Scaling beyond isolated processors demands entanglement links between qubits across adjacent processors via photonic quantum networking. This remains the biggest technical barrier to modular, distributed quantum computers. Nu Quantum’s Entanglement Fabric provides the modular, interoperable architecture and high-rate connectivity needed for fault-tolerant, distributed quantum computing.

Nu Quantum’s fundraise will accelerate development and deployment, advancing quantum networking in performance and scale. Building on its Qubit-Photon Interface (2024) and Quantum Networking Unit (2025), the roadmap leverages Distributed Quantum Error Correction. Funding also supports international expansion, including its US presence and Strategic Advisory Board, while strengthening collaboration through the Quantum Datacenter Alliance and QPU partnerships for network-processor integration.
