Quantum Networking Unit (QNU)
A 19-inch rack-mount system hosting photonic integrated circuits that distributes quantum entanglement across connected processors. Launched in June 2025, the QNU provides reconfigurable connectivity between quantum computing nodes for datacenter-scale quantum architectures. Nu Quantum describes it as the world's first product of its kind, delivering 99.7% entanglement fidelity at a 1 MHz attempt rate.
Qubit-Photon Interface (QPI)
A hardware component that bridges quantum processors to an optical network by efficiently coupling light from qubits. Launched in October 2024, the QPI is designed to work across multiple qubit modalities, allowing different quantum processor types to connect to the same networking infrastructure. It is the first link in Nu Quantum's entanglement distribution chain.
Entanglement Fabric
Nu Quantum's distributed quantum computing architecture, combining its networking hardware with a software abstraction layer for qubit-agnostic application development. The Entanglement Fabric defines how modular quantum processors interconnect and scale, and is the overall framework that the QPI and QNU are designed to populate.
About
Nu Quantum is a Cambridge-based quantum networking company, founded in 2018 as a spin-out from the University of Cambridge's Cavendish Laboratory. The company develops the physical hardware needed to link quantum processors together, treating quantum networking the same way classical networking underpins cloud and HPC infrastructure today.
