Nu Quantum Announces $60 Million Series A Round
Despite significant enthusiasm for quantum computing, progress in the field has been limited by the challenge of isolated quantum machines. Nu Quantum, a Cambridge-based startup, is addressing this issue by developing a network that connects distinct quantum processors into an integrated distributed system.
The company recently announced the successful closure of a $60 million Series A funding round, led by National Grid Partners, with participation from Gresham House Ventures, Morpheus Ventures, and established investors such as Amadeus Capital, IQ Capital, Ahren Capital, and Sumitomo (Presidio Ventures).
This funding marks the largest Series A for a pure-play quantum networking enterprise and sets a new record within the UK’s quantum sector. Founded in 2018 by University of Cambridge physicist Dr Carmen Palacios-Berraquero, Nu Quantum was established in response to the industry’s focus on single-processor systems and the resulting connectivity challenges.
Dr Palacios-Berraquero stated, “When we launched seven years ago, networked or distributed quantum computing was not widely considered a scaling strategy. We identified it as one of the pressing problems in the industry and have since made considerable progress in shaping both the market and technology.”
She further commented, “As the company has evolved, I am proud of our culture of innovation, collaboration, and diversity, all united under the goal of advancing quantum computing for societal benefit.”
Nu Quantum’s platform leverages its proprietary Entanglement Fabric, a quantum networking layer that utilizes photons to entangle and connect quantum processors with high fidelity. This enables a modular architecture capable of integrating various qubit types, including superconducting, trapped-ion, and neutral-atom qubits.
In contrast to companies such as PsiQuantum, Quantinuum, and Rigetti, Nu Quantum is pursuing quantum networking as the pathway to fault tolerance. The company’s hardware portfolio includes the Qubit-Photon Interface, launched in 2024, and the Quantum Networking Unit (QNU), introduced in 2025.
Looking ahead, Nu Quantum intends to expedite the development of its distributed computing platform and advance toward a fault-tolerant quantum supercomputer. Efforts will be concentrated on scaling technology from prototype to deployment, developing the Entanglement Fabric roadmap, investing in Distributed Quantum Error Correction, and expanding the Quantum Datacenter Alliance (QDA).
