What Nu Quantum does

Nu Quantum is a Cambridge, UK-based quantum networking company founded in 2018 by Dr. Carmen Palacios-Berraquero as a spin-out of the University of Cambridge's Cavendish Laboratory. The company is positioned as the category creator in distributed quantum computing, building the 'Entanglement Fabric' — a photonic networking layer that interconnects multiple quantum processors (QPUs) into a single, more powerful distributed quantum computer rather than relying on monolithic million-qubit architectures. Its core hardware products are the Qubit-Photon Interface (QPI), an optical microcavity-based network interface that couples qubits to the photonic network across trapped-ion, neutral-atom and (in principle) superconducting modalities, and the Quantum Networking Unit (QNU), a 19-inch rack-mounted, datacentre-compatible system combining a dynamic entangler (up to 99.7% entanglement fidelity, sub-microsecond circuit switching) with a real-time quantum network orchestrator (300 ns control latency) and CERN White Rabbit sub-nanosecond timing synchronisation. The company also publishes distributed quantum error-correction research (e.g., Floquet and hyperbolic codes) underpinning the technical feasibility of its architecture.

The business is pre-commercial and historically funded by a mix of equity capital and non-dilutive government grants. Cumulative funding exceeds $70M across a £2.1M seed (2020), a £7M pre-Series A (Nov 2023) and an oversubscribed $60M Series A (Dec 2025) led by National Grid Partners — the largest pure-play quantum networking financing on record. Revenue streams to date comprise grant income (Innovate UK Quantum Missions Pilot, SBRI, NSSIF, Spanish SETT) rather than product sales, and commercial pricing is not publicly disclosed. The go-to-market motion is enterprise-direct, targeting qubit hardware companies (Atom Computing, Quantinuum, QuEra, OQC), classical networking incumbents (Cisco, NTT Data), national quantum programmes (UK NQCC) and data-centre operators, with the founder-led Quantum Datacenter Alliance functioning as both a technical standards body and channel. The company operates from Cambridge (HQ + research labs), Los Angeles (US business office, opened 2024), and a Madrid-based Spanish subsidiary (established January 2026 with €9.75M SETT funding) focused on QNU industrialisation and photonic integrated circuit development.

Revenue model

1. Future Hardware/Networking Product Sales: Nu Quantum is pre-commercial but transitioning from breakthrough innovation toward commercial rollout of its quantum networking solutions. The Series A funding is intended to support product development and deployment of its Entanglement Fabric roadmap, suggesting forward revenue from sales of Quantum Networking Units (QNUs), Qubit-Photon Interfaces (QPIs) and related photonic networking subsystems to qubit providers and data centre customers.
2. Government/Grant Funding (R&D): Nu Quantum has historically drawn revenue from non-dilutive funding sources including Innovate UK Quantum Missions Pilot grants, SBRI funding from the UK Government, NSSIF investment, and SETT (Spain) investment tied to its Spanish subsidiary. The QNU was developed under the UK Government's Small Business Research Initiative (SBRI).

Core offering

Nu Quantum builds photonic quantum networking hardware and software that interconnect multiple quantum processors into a single distributed quantum computer. Its core deliverables are the Entanglement Fabric networking platform, the Qubit-Photon Interface (QPI) optical module that couples qubits to the photonic network, and the rack-mounted Quantum Networking Unit (QNU) that dynamically distributes entanglement across processors. Customers are quantum computing hardware companies, datacentre operators and national quantum programmes seeking modular scale-out beyond monolithic chip designs.

Product overview

Nu Quantum offers a platform-plus-modules architecture rather than a single unified product, centred on its proprietary Entanglement Fabric networking platform for distributed quantum computing scale-out. The two flagship hardware modules — the Qubit-Photon Interface (QPI), which couples individual qubits to the photonic network, and the rack-mounted Quantum Networking Unit (QNU), which dynamically distributes entanglement across processors with CERN White Rabbit timing integration — together implement the Entanglement Fabric and connect to multiple qubit modalities (trapped ion, neutral atom, superconducting). Underpinning theoretical capabilities include Distributed Quantum Error Correction research and Floquet codes theory work, while ecosystem efforts include the Quantum Datacenter Alliance (QDA) and a Spanish subsidiary focused on photonic integrated circuits (PICs) industrialisation.

Products and services

• Entanglement Fabric Nu Quantum's core networking platform and architectural blueprint for distributed quantum computing. Weaves multiple quantum processors (QPUs) together into a modular, scalable, fault-tolerant architecture by integrating photonic hardware with networking protocols, and acts as an abstraction layer enabling qubit-agnostic compilation and software stack development across trapped-ion, neutral-atom and superconducting modalities. Designed for quantum hardware vendors, datacentre operators and national quantum programmes seeking modular scale-out.
• Quantum Networking Unit (QNU) A 19-inch rack-mounted, air-cooled, datacentre-ready photonic system that brokers dynamically reconfigurable entanglement links between multiple quantum processors. Combines a dynamic entangler system (sub-microsecond circuit switching, less than 3x10-3 Bell-state measurement error, up to 99.7% remote entanglement fidelity) with a real-time quantum network orchestrator (300 ns control latency, MHz entanglement attempt rate), and integrates CERN White Rabbit timing for sub-nanosecond synchronisation. Designed to entangle a cluster of four trapped-ion quantum processors.
• Qubit-Photon Interface (QPI) A network-interface-card equivalent that couples qubits inside each quantum processing core to the wider photonic networking infrastructure. Based on optical microcavity technology integrated into custom-built ion traps, it is modality-adaptable (trapped-ion, neutral-atom) and is the bridge enabling high-performance entanglement links between qubits across nodes. Project HyperIon targets a 50x increase in entanglement rate with state-of-art remote fidelity.
