On January 28, 2026, the Spanish government, through the Spanish Society for Technological Transformation (SETT), invested €9.75 million (~$11.6 million) as part of Nu Quantum’s €51 million Series A funding round. The investment was made under the Ministry for Digital Transformation and Public Administration and aligned with Spain’s National Strategy for Quantum Technologies and the PERTE Chip microelectronics program.
As part of the agreement, Nu Quantum committed to opening a Spanish subsidiary in Madrid focused on industrializing its Quantum Networking Unit (QNU) and developing photonic integrated circuits (PICs) for distributed quantum computing. The subsidiary was expected to create more than 30 high-skilled technical jobs. The investment was structured through the public-private model promoted by SETT.
The QNU is a rack-mounted system designed to orchestrate real-time entanglement between discrete quantum processing units, enabling multiple smaller quantum computers to function as a single, more powerful system. Nu Quantum is a University of Cambridge spin-out founded in 2018 and led by Spanish quantum physicist Dr. Carmen Palacios-Berraquero.
