Nu Quantum Raises €55M to Advance Quantum Computer Networking
Quantum computing, Deep tech
💎 Nu Quantum closes the largest-ever Series A round for a quantum networking company, signaling a shift toward modular, distributed quantum architectures as the industry’s path to scale.
Nu Quantum, a UK-based deep-tech company pioneering distributed quantum computing, has raised $60 million (≈€55 million) in an oversubscribed Series A round — the largest financing ever for a pure-play quantum networking company and the biggest quantum Series A to date in the UK. The round was led by National Grid Partners, with new participation from Gresham House Ventures and Morpheus Ventures, alongside continued backing from Amadeus Capital Partners, IQ Capital, Ahren Capital, Cambridge Enterprise Ventures, East Innovate, NSSIF, and Sumitomo (Presidio Ventures).
The capital will be used to accelerate Nu Quantum’s roadmap toward fault-tolerant quantum computing by interconnecting quantum processors into a distributed system — a market the company estimates could unlock a €900+ billion opportunity globally.

Why quantum networking matters now
While much of the quantum industry has focused on improving individual quantum processors, real-world utility will require systems with orders of magnitude more qubits than currently exist. Nu Quantum’s thesis is that this scale will not come from monolithic machines, but from networked quantum processors, connected in a modular, data-center-like architecture.
This mirrors the evolution of classical computing, where networking enabled cloud computing, hyperscale data centers, and high-performance computing. Nu Quantum aims to replicate this paradigm for quantum through its proprietary networking layer, known as the Entanglement Fabric.
The Entanglement Fabric
Nu Quantum’s technology focuses on creating high-fidelity, high-rate entanglement links between quantum processors using photonic networking — widely regarded as one of the hardest technical challenges in the field today. Its modular and interoperable architecture is designed to work across multiple qubit modalities, making it adaptable to a rapidly evolving hardware landscape.
The company has already demonstrated key subsystems, including a Qubit–Photon Interface (2024) and a Quantum Networking Unit (2025), positioning it ahead of many peers in translating theory into deployable infrastructure.
Founder and investor perspectives
“When we launched seven years ago, very few were thinking about networked or distributed quantum computing as a strategy for scaling,” said Dr. Carmen Palacios-Berraquero, Founder and CEO of Nu Quantum. “This investment validates both our vision and the maturity of our solution as the path forward for the industry.”
From the investor side, Steve Smith, Chief Strategy and Regulation Officer at National Grid and President of National Grid Partners, emphasized the near-term impact: “We are closer to quantum computing having real-world impact than many people think. Nu Quantum is bringing this powerful technology closer to market.”
Global expansion and ecosystem building
The funding will also support Nu Quantum’s international expansion, particularly in Europe and the United States. Following the opening of its Los Angeles office in 2024, the company has assembled a US-based Strategic Advisory Board including former leaders from IBM, Cisco, and AWS Braket.
Nu Quantum continues to convene industry players through the Quantum Datacenter Alliance (QDA), working closely with quantum processor manufacturers to integrate networking directly into next-generation quantum systems.
A signal for the quantum market
This round underscores a growing consensus in the quantum sector: scaling, not isolated performance gains, is the defining challenge of the next decade. By positioning itself as the networking layer for distributed quantum data centers, Nu Quantum is betting that the future of quantum advantage will look more like today’s cloud infrastructure — interconnected, modular, and built for scale.
If that thesis holds, this Series A may be remembered not just as a funding milestone, but as a structural turning point for the quantum computing industry.
