Cambridge’s Nu Quantum nets $60M to build the ‘internet for quantum machines’ - Tech Funding News
Summarize this article with:
For all the excitement surrounding quantum computing, the field has long been constrained by one stubborn fact: even the most advanced quantum machines remain islands. That’s the challenge Nu Quantum, a Cambridge-born startup, set out to solve. Its mission is to create the internet of quantum computers, connecting separate quantum processors into a distributed network that operates as a single system. The company just closed a $60 million Series A, led by National Grid Partners and joined by Gresham House Ventures, Morpheus Ventures, and long‑time backers including Amadeus Capital, IQ Capital, Ahren Capital, and Sumitomo (Presidio Ventures). It’s the biggest funding round ever for a pure‑play quantum networking company and the largest Series A in the UK’s quantum sector. A modular approach that can integrate different types of qubits The company was founded in 2018 by Dr Carmen Palacios‑Berraquero, a physicist from the University of Cambridge who recognised that the industry’s obsession with single-processor systems overlooked a bottleneck: connectivity. Palacios-Berraquero 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. We’ve made great strides in shaping the market and the technology since then.” She added, “As we’ve grown, I’m proud that we’ve created a culture defined by fearless innovation and fuelled by collaboration and diversity, all under a shared mission to accelerate quantum computing for good. “ Nu Quantum’s platform is built around its Entanglement Fabric, a quantum networking layer that uses photons to entangle and connect processors with high fidelity. The result is a modular approach that can integrate different types of qubits, including superconducting, trapped‑ion, and neutral‑atom qubits. Unlike PsiQuantum, Quantinuum, and Rigetti, Nu Quantum bets that quantum networking will win the race to fault tolerance. The company’s hardware includes the Qubit‑Photon Interface (unveiled in 2024) and the Quantum Networking Unit (QNU) (introduced in 2025). What’s next? Nu Quantum plans to accelerate the development of its distributed computing platform and move closer to its vision of a fault‑tolerant quantum supercomputer. The company is now focusing on scaling its technology from prototype to deployment. It will advance its Entanglement Fabric roadmap, invest in Distributed Quantum Error Correction, and expand its Quantum Datacenter Alliance (QDA).
