Spain Invests €9.75M ($11.6M USD) in Nu Quantum to Establish Distributed Quantum Networking Hub Nu Quantum has announced that the Spanish Government, through the Spanish Society for Technological Transformation (SETT), has invested €9.75 million ($11.6 million USD) as part of the company’s $60 million (€51 million) Series A funding round. The investment is a strategic component of Spain’s PERTE Chip and the National Strategy for Quantum Technologies, aimed at securing a leading position in the European quantum ecosystem. As part of the agreement, Nu Quantum will open a Spanish subsidiary in Madrid focused on the industrialization of quantum networking and photonic infrastructure for Distributed Quantum Computing (DQC). Technical Focus: Industrializing the Quantum Networking Unit (QNU) The Spanish subsidiary will serve as a primary center for the production and refinement of Nu Quantum’s Quantum Networking Unit (QNU). The QNU is the industry’s first industrialized, 19-inch rack-mounted system designed to orchestrate real-time entanglement between discrete quantum processing units (QPUs). By integrating sub-microsecond circuit switching and high-fidelity photonic interfaces, the QNU allows multiple smaller quantum computers to function as a single, unified, and more powerful system. This “scale-out” approach is critical for overcoming the physical footprint and thermal limitations that currently restrict the number of qubits on a single processor.
Advancing Photonic Integrated Circuits (PICs) A key objective of the new Madrid-based facility is the development of advanced Photonic Integrated Circuits (PICs). These chips are essential for creating ultrafast, low-loss switching and sensing modules that distribute quantum states with minimal decoherence. By utilizing PIC-based hardware, Nu Quantum aims to achieve the high entanglement rates and low error thresholds (currently targeting 99.7% accuracy in maintaining quantum links) required for fault-tolerant distributed computation. This infrastructure will align with Spain’s domestic photonic ecosystem, leveraging existing strengths in semiconductor design and manufacturing.
Distributed Quantum Error Correction and “Entanglement Fabric” The investment will accelerate the deployment of Nu Quantum’s Entanglement Fabric™, a modular architecture that separates the control and orchestration planes from the optical plane. This fabric acts as an abstraction layer, enabling hardware-agnostic connectivity across different qubit modalities, such as trapped ions and superconducting qubits. Furthermore, the collaboration will explore distributed quantum error correction (QEC) codes, which utilize non-local connectivity to reduce the physical qubit overhead typically required to correct computational errors in large-scale systems. Strategic Impact and European Technological Sovereignty The establishment of Nu Quantum’s Spanish subsidiary is expected to create over 30 highly skilled technical jobs and strengthen European technological sovereignty in the quantum sector. Led by founder and CEO Dr. Carmen Palacios-Berraquero, a Spanish quantum physicist, the project facilitates a “discovery-to-deployment” pathway within the EU’s NextGenerationEU framework. The hub will serve as a magnet for international talent and investment, providing the secure, scalable networking infrastructure necessary to transition quantum computing from laboratory experiments to commercial industrial applications in drug discovery, energy optimization, and financial modeling.
