Sparrow Quantum is a Danish spin-out from the Niels Bohr Institute that designs and manufactures the Sparrow Core, a photonic chip able to generate on-demand single photons—an essential building block for photonic quantum computers and secure quantum communication networks. Its deterministic photon source operates at room temperature, offers strong noise resistance, and is designed for scalable integration into standard microchips, avoiding the cryogenic cooling required by many competing platforms. The technology is already deployed by several European technology companies, demonstrating industrial readiness. With fresh capital, Sparrow Quantum plans to scale up chip production, expand globally, and accelerate development of its next generation of quantum chips. The company positions itself as a pillar of Denmark’s and Europe’s quantum-technology strategy, leveraging research momentum from the Niels Bohr Institute. The recent Series A round is reported as the largest quantum-technology investment to date in the Nordics, underscoring significant investor confidence in the firm’s commercial prospects.
