Nu Quantum, a UK-based pioneer in distributed quantum computing, has closed a $60 million oversubscribed Series A round, marking the largest investment to date for a pure-play quantum networking company and the biggest Series A ever raised in the UK quantum sector.
The financing is intended to accelerate the company’s efforts to connect quantum processors into distributed, fault-tolerant systems – an approach Nu Quantum believes is essential to unlocking what analysts project could become a ~$1 trillion global quantum computing market.
Led by National Grid Partners, the funding round drew participation from Gresham House Ventures and Morpheus Ventures, with continued support from existing backers including Amadeus Capital Partners, IQ Capital, Ahren Capital, Cambridge Enterprise Ventures, East Innovate, NSSIF, and Sumitomo’s Presidio Ventures.
While much of the quantum computing industry has focused on improving the power and stability of individual processors, Nu Quantum represents a strategic shift toward solving quantum computing’s scalability bottleneck. Current quantum systems operate in isolation, and even the most advanced architectures have only a fraction of the qubits required for large-scale commercial applications. Real fault tolerance – a prerequisite for solving complex scientific, industrial, and national security problems – will require systems thousands of times larger than those available today.
Nu Quantum approaches this challenge by building a quantum networking stack that links many smaller processors into a modular, distributed architecture. Its “Entanglement Fabric” lays the foundation for quantum datacenters, mirroring the role that classical networking played in enabling cloud hyperscalers, AI accelerators, and high-performance computing clusters. The design is qubit-agnostic, giving it compatibility across modalities and positioning the company as a potential backbone provider for future quantum computing environments.
Dr. Carmen Palacios-Berraquero, CEO and cofounder of Nu Quantum, said the company’s focus on networking emerged long before distributed quantum computing entered the mainstream. She noted that scalability has become one of the most urgent engineering challenges facing the sector. “As we’ve grown, I’m proud we have created a culture defined by fearless innovation and fueled by collaboration and diversity under a shared mission to accelerate quantum computing for good,” she said, adding that the Series A round validates the company’s early bet that networking would be the decisive path forward.
Investors pointed to both technological progress and market timing as reasons for their support. Steve Smith, Chief Strategy and Regulation Officer at National Grid and President of National Grid Partners, said that quantum computing is advancing faster than many expect and that Nu Quantum is helping move the technology toward practical deployment. Representatives from Gresham House Ventures and Morpheus Ventures highlighted the company’s potential to address scaling and fidelity constraints—issues that remain unsolved across the broader quantum ecosystem.
The core of Nu Quantum’s technology involves generating and distributing high-quality entanglement between qubits housed in separate processors via photonic links. Achieving fast, high-fidelity entanglement at scale is widely considered the largest scientific challenge blocking the emergence of modular quantum computers and large-scale quantum communication networks. The company’s Entanglement Fabric is designed to deliver these entanglement rates with interoperability across different qubit systems, offering a potential template for quantum datacenters supporting future industrial and scientific workloads.
Nu Quantum plans to use its new funding to accelerate product development and expand internationally. The company is moving forward with a roadmap that builds on its Qubit-Photon Interface (2024) and Quantum Networking Unit (2025) to push network performance and system-level integration. The work will be informed by Nu Quantum’s contributions to distributed quantum error correction, which is considered essential for fault-tolerant systems. Expansion efforts include strengthening its presence in Europe and the United States, where it opened a Los Angeles office in 2024 and established a Strategic Advisory Board that includes industry veterans such as Dr. Robert Sutor (formerly IBM), Roland Acra (formerly Cisco CTO), and Richard Moulds (former head of AWS Braket).
Nu Quantum is also facilitating collaboration through the Quantum Datacenter Alliance, positioning its networking technology as the connective layer for quantum processors built by multiple vendors. The company sees distributed quantum computing as not only a means to scale but also the architecture most likely to support commercial applications ranging from molecular simulation and advanced materials design to financial optimization and next-generation energy systems.
As the global race for quantum advantage intensifies, Europe is seeking to expand its role in the ecosystem. Nu Quantum’s approach would align with the region’s goal of balancing innovation, digital sovereignty, and international collaboration. The company’s expansion and substantial Series A demonstrate growing investor confidence in quantum networking as a critical enabler of the next generation of computing.
