Nu Quantum

Nu Quantum is a UK quantum networking company founded in 2018 as a University of Cambridge spinout that develops quantum photonic hardware including room-temperature single-photon sources and detectors for quantum networking applications, pioneering breakthrough Qubit-Photon Interfaces (QPIs) that enable 100x better entanglement rates than current lab state-of-the-art for distributed quantum computing networks, awarded £2.3 million UK government contract to deliver the world's first modular rack-mount scalable quantum data center prototype with Cisco, building industrialized distributed quantum computing systems at the UK's National Quantum Computing Centre using proprietary optical microcavity technology with micron-level precision and sub-80 picometre stability for quantum processor networking.

2025 Developments: In March 2025, Nu Quantum partnered with Cisco, NTT DATA, OQC, QphoX, Quantinuum, and QuEra to launch Quantum Datacenter Alliance. In June 2025, launched Quantum Networking Unit (QNU), first industrialized rack-mounted system for distributing entanglement. Hosted inaugural Quantum Datacenter Alliance Forum in London (June 2025).
