Raised $60m Series A, largest quantum-networking round globally
UK Startups and Innovation: DSIT scorecard maps the funding barbell- What is quantum networking and how is it different from quantum computing?
- Quantum networking transmits quantum states between nodes to link quantum computers or establish unbreakable communication channels, using hardware at the physical layer. Quantum computing processes information using qubits. NuQuantum focuses on the networking layer rather than the computing layer.Source: Lowdown
- How much did NuQuantum raise and why is it a record?
- NuQuantum raised $60m in a Series A, described as the largest quantum-networking fundraise globally at the time of closing. Most quantum investment has historically gone to computing rather than networking hardware, making this scale unusual for the networking segment.Source: Lowdown
- Why is NuQuantum based in Cambridge?
- Cambridge hosts one of the UK's leading quantum research ecosystems, anchored by the Cavendish Laboratory and the National Quantum Computing Centre. NuQuantum draws on this research and talent base for its quantum networking hardware development.
- What does the UK government's Quantum Sector Plan say about NuQuantum?
- DSIT's Quantum Sector Plan, published alongside its June 2026 funding scorecard, cited NuQuantum's Series A as evidence of UK leadership in the quantum networking segment.Source: Lowdown
Background
NuQuantum closed a $60m Series A in June 2026, described at the time of closing as the largest quantum-networking fundraise globally. The Cambridge-based company builds hardware and software for quantum networks, which aim to connect quantum computers and enable quantum-secure communications. The raise was recognised in the DSIT Quantum Sector Plan as evidence of UK leadership in quantum networking, a segment where NuQuantum competes with US and Chinese programmes.
Quantum networking is distinct from Quantum computing: rather than processing information using qubits, it transmits quantum states across physical infrastructure to link multiple quantum nodes or establish cryptographically unbreakable communication channels. NuQuantum's approach addresses the hardware layer of this transmission problem. Cambridge's quantum ecosystem, built around the Cavendish Laboratory and the National Quantum Computing Centre, provides the research and talent base that underpins the company.
A $60m Series A in quantum networking is notable because the segment has historically struggled to attract capital at scale. Most quantum investment has concentrated in computing rather than networking hardware. NuQuantum's ability to close this round at a record size suggests growing institutional recognition that quantum networking is a parallel infrastructure layer, not a secondary feature of quantum computers.
