Nu Quantum lands $60M to scale quantum networking
UK-based quantum networking startup Nu Quantum has raised a $60m Series A round, marking the largest financing to date for a pure-play quantum networking company. The oversubscribed round underlines growing confidence that distributed quantum computing will be key to scaling the technology beyond today’s limits.
Record Series A for quantum networking
The round was led by National Grid Partners, with participation from Gresham House Ventures and Morpheus Ventures, alongside continued backing from existing investors including Amadeus Capital Partners, IQ Capital, Ahren Capital, Cambridge Enterprise Ventures, East Innovate, NSSIF and Sumitomo (Presidio Ventures). According to Nu Quantum, it is also the largest quantum Series A ever raised in the UK.
Founded in Cambridge, Nu Quantum positions itself as a category creator in distributed quantum computing. Instead of focusing on ever-larger monolithic quantum processors, the company is betting on networking smaller quantum processors together to form a more powerful, fault-tolerant system. The funding will be used to accelerate development of its quantum networking stack and to support international expansion in Europe and the US.
Dr. Carmen Palacios-Berraquero, founder and CEO of Nu Quantum, said: “When we launched seven years ago, very few were thinking about networked or distributed quantum computing as a strategy for scaling, but we saw it as one of the most urgent and challenging outstanding problems in the industry, and set out to solve it.”
Entanglement Fabric as the scaling layer
At the core of Nu Quantum’s approach is its Entanglement Fabric, a modular quantum networking layer designed to link qubits across separate processors using photonic interconnects. High-fidelity, high-rate entanglement between processors remains one of the hardest challenges in quantum computing, and a major barrier to building systems with thousands or millions of qubits.
Nu Quantum argues that distributed architectures will ultimately mirror the evolution of classical computing, where networking enabled cloud data centers, AI infrastructure and high-performance computing. Importantly, the company says its architecture supports multiple qubit modalities instead of locking customers into a single hardware platform.
Steve Smith, chief strategy and regulation officer of National Grid and president of National Grid Partners, said: “We are closer to quantum computing having an impact on businesses and lives than many people think. Nu Quantum is at the forefront of bringing this powerful technology closer to market and using it to solve real-world challenges today.”
Roadmap, products and expansion
The new capital will fund the next phase of product development following Nu Quantum’s Qubit-Photon Interface, introduced in 2024, and its Quantum Networking Unit launched in 2025. The company is also building its system architecture around distributed quantum error correction.
On the business side, Nu Quantum is expanding its footprint in the US, building on its Los Angeles office and a strategic advisory board that includes former executives from IBM, Cisco and Amazon Braket. It will also continue to grow the Quantum Datacenter Alliance, working with quantum processor partners to integrate networking and compute at scale.
