Nu Quantum, the distributed quantum computing provider, has reportedly closed its $60 million Series A round led by National Grid Partners, including participation from Gresham House Ventures and Morpheus Ventures, and support from existing investors Amadeus Capital Partners, IQ Capital, Ahren Capital, Cambridge Enterprise Ventures, East Innovate, NSSIF, and Sumitomo (Presidio Ventures).
It is the largest financing round ever raised by “a pure-play quantum networking company, and the largest quantum Series A in the UK to date.”
The funding will accelerate Nu Quantum’s mission “to reach fault tolerance by interconnecting quantum processors into a distributed quantum computer, unlocking the projected $1 trillion quantum computing market.”
Quantum computers have the potential to solve problems “that will always be beyond the reach of any classical supercomputer.”
Applications could include modelling molecules on “an atomic level to simulation and optimisation of systems with millions of interdependent parameters, like electric grids or financial markets.”
Until now, the quantum computing industry has “focused on improving individual quantum processors.”
But achieving real utility and fault tolerance will “require scaling to systems with 1,000x more qubits than exist today.”
Nu Quantum’s quantum networking stack “opens a new approach: enabling quantum computers to scale by weaving individual processors into a modular, distributed computing fabric.”
Networking has played a critical role in the “classical computing industry, enabling Cloud and AI data centers, and High Performance Computing.”
Nu Quantum’s belief is that the “mass commercialisation of quantum computing will happen via distributed architectures in quantum datacenters, underpinned by Nu Quantum’s networking infrastructure – the Entanglement Fabric.”
Crucially, Nu Quantum’s architecture is adaptable “to support scaling for multiple different Qubit modalities.”
Quantum computers rely on “qubits and high-quality entanglement between them to run powerful computations.”
To move beyond isolated processors, they must create “entanglement links between qubits in adjacent processors, via photonic quantum networking.”
Achieving this with high-fidelity and high rate is today the single biggest technical challenge “preventing the modular scaling of quantum computers, communication and sensor networks.”
Nu Quantum’s networking layer – called the Entanglement Fabric – will provide the “architecture and connectivity at the rates necessary for distributed, fault-tolerant computing.”
Nu Quantum’s fundraise will drive the “next phase of product development and deployment, delivering on a roadmap to advance quantum networking in both performance and scale.”
Nu Quantum will build on “the success of its quantum networking subsystems: the Qubit-Photon Interface in 2024, and the Quantum Networking Unit in 2025.”
The overall system architecture will be informed by its “work on Distributed Quantum Error Correction.”
The funding will also support Nu Quantum’s international expansion, including the “growth of its presence in Europe and the US.”
After the opening of its LA office in 2024, the company has built a US-based Strategic Advisory Board, “including Dr. Robert Sutor, formerly of IBM, and Roland Acra, former CTO of networking firm Cisco System, and Richard Moulds, former Head of Amazon Braket, the AWS Quantum Computing as a Service platform.”
Nu Quantum will continue to bring together the ecosystem “under the umbrella of the Quantum Datacenter Alliance (QDA), and work with Quantum Processing Unit (QPU) partners to advance network-processor integration.”
