Nu Quantum has unveiled its Quantum Networking Unit (QNU), a modular and datacentre-ready system designed to enable high-fidelity, real-time entanglement distribution across quantum processors. Positioned as a foundational component for scaling distributed quantum computing systems, the QNU integrates a photonic dynamic entangler with a low-latency quantum network orchestrator in a 19″ rack-mounted form factor.
The system is designed to connect clusters of trapped-ion processors via dynamically switchable optical paths and synchronised control. The entangler enables sub-microsecond circuit switching with entanglement fidelities of up to 99.7%, while the orchestrator delivers 300 ns latency and MHz-scale entanglement attempt rates. This architecture aims to support high-throughput, fault-tolerant networking across datacentre environments.
Developed under the UK Government’s Small Business Research Initiative (SBRI), the QNU will be deployed in Nu Quantum’s multi-node networking testbed and is compatible with future integration of timing solutions such as CERN’s White Rabbit protocol. The company’s broader roadmap includes combining this system with previously developed qubit-photon interfaces to support abstracted, modular quantum layers across heterogeneous processors.
The QNU features a modular control-optics separation architecture for flexibility across modalities and configurations. Nu Quantum developed the platform in collaboration with qubit vendors and integrators to ensure commercial viability for scaling distributed quantum systems. The launch marks a shift from prototype lab demonstrations to deployable quantum interconnects targeting commercial utility.
