National Grid Partners led a $60 million Series A funding round for Nu Quantum, a leader in distributed quantum computing, with participation from Gresham House Ventures and Morpheus Ventures. This oversubscribed investment will accelerate Nu Quantum’s Entanglement Fabric roadmap, designed to interconnect quantum processors and scale computing power beyond current limitations. Nu Quantum’s approach focuses on networking individual quantum processors into a modular, distributed computing fabric, aiming to achieve the 1,000x qubit increase necessary for fault tolerance and unlock the projected $1 trillion quantum computing market. This funding represents the largest ever raised by a pure-play quantum networking company and the largest quantum Series A in the UK to date.
Nu Quantum’s Series A Funding and Expansion
Nu Quantum recently closed a $60 million Series A funding round, the largest of its kind for a pure-play quantum networking company and in the UK to date. Led by National Grid Partners with participation from Gresham House Ventures and Morpheus Ventures, this oversubscribed funding will accelerate the company’s “Entanglement Fabric” roadmap. This fabric is a modular, interoperable networking layer designed to interconnect quantum processors, ultimately aiming to achieve fault tolerance and unlock the potential of a $1 trillion quantum computing market.
The funding will also support Nu Quantum’s expansion, including growth in Europe and the US, following the 2024 opening of its Los Angeles office. A US-based Strategic Advisory Board has been established with experts from IBM, Cisco, and Amazon Braket, indicating a focus on industry collaboration. Nu Quantum plans to build on its existing quantum networking subsystems – the Qubit-Photon Interface (2024) and the Quantum Networking Unit (2025) – and advance Distributed Quantum Error Correction.
Nu Quantum’s “Entanglement Fabric” addresses a critical technical challenge: achieving high-fidelity, high-rate entanglement between qubits in adjacent processors. The company believes mass commercialization of quantum computing will rely on distributed architectures within quantum datacenters, underpinned by its networking infrastructure. This approach differs from focusing solely on improving individual quantum processors, aiming instead to scale systems to the 1,000x increase in qubits needed for practical applications.
The Need for Quantum Networking and Scaling
Nu Quantum recently secured $60 million in Series A funding, the largest of its kind for a pure-play quantum networking company and in the UK to date. This investment will accelerate the company’s “Entanglement Fabric” roadmap, aiming to interconnect quantum processors into a more powerful, distributed quantum computer. This approach is seen as critical for achieving fault tolerance and unlocking the potential of the projected $1 trillion quantum computing market, as scaling beyond individual processors is currently a major challenge.
Nu Quantum’s solution focuses on quantum networking, specifically creating entanglement links between qubits in different processors using photonic technology. The source highlights that achieving high-fidelity and high-rate entanglement is the biggest technical hurdle to modular scaling. The “Entanglement Fabric” aims to provide the necessary architecture and connectivity for distributed, fault-tolerant computing, mirroring the role networking played in scaling classical computing infrastructure like cloud data centers.
The company’s future plans include building on successful developments like the Qubit-Photon Interface and Quantum Networking Unit, and expanding its presence internationally with a growing US-based Strategic Advisory Board. Nu Quantum intends to work with Quantum Processing Unit (QPU) partners, under the umbrella of the Quantum Datacenter Alliance, to advance network-processor integration, ultimately aiming to accelerate quantum computing for widespread application.
Entanglement Fabric: Nu Quantum’s Core Technology
Nu Quantum’s core technology is the Entanglement Fabric, a modular and interoperable networking layer designed to interconnect quantum processors. This fabric aims to overcome current limitations by enabling the scaling of quantum computers through a distributed architecture. Crucially, the Entanglement Fabric focuses on creating high-fidelity, high-rate entanglement links between qubits in adjacent processors via photonic quantum networking – a significant technical challenge preventing modular scaling today.
The Entanglement Fabric builds upon Nu Quantum’s advancements, including the Qubit-Photon Interface (2024) and the Quantum Networking Unit (2025). This architecture is informed by the company’s work on Distributed Quantum Error Correction, supporting the goal of reaching fault tolerance. Nu Quantum believes this approach, mirroring the role of networking in classical computing, will be key to unlocking the projected $1 trillion quantum computing market.
Nu Quantum’s Entanglement Fabric is intended to facilitate a move towards quantum datacenters and distributed quantum computing. The company aims to create a scalable solution, adaptable to multiple qubit modalities, to address the limitations of isolated quantum processors. Through this technology, Nu Quantum is focused on accelerating the path to fault tolerance and realizing breakthroughs across various industries.
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.

Future Plans: Advancing Distributed Quantum Computing
Nu Quantum’s $60 million Series A funding will accelerate product development and deployment, advancing quantum networking performance and scale. Building on successes like the 2024 Qubit-Photon Interface and the 2025 Quantum Networking Unit, future work will be informed by their pioneering Distributed Quantum Error Correction research. This funding will also support international expansion, including growth in Europe and the US, following the 2024 opening of a Los Angeles office and the formation of a US-based Strategic Advisory Board.
The company’s core focus is the “Entanglement Fabric,” a modular, interoperable networking layer designed to interconnect quantum processors, enabling a more powerful distributed quantum computer. Nu Quantum believes this approach is crucial for achieving fault tolerance and scaling beyond current qubit limitations – aiming for systems with 1,000x more qubits. This networking infrastructure is seen as analogous to the role networking played in scaling classical computing for Cloud and AI data centers.
Nu Quantum plans to collaborate with Quantum Processing Unit (QPU) partners and foster ecosystem development through the Quantum Datacenter Alliance (QDA). The company’s technology addresses a key technical challenge: creating high-fidelity, high-rate entanglement links between qubits in adjacent processors via photonic quantum networking – a critical step toward modular scaling of quantum computers, communication, and sensor networks.
