Sparrow Quantum Aps

Based in Copenhagen, Denmark, and founded in 2015 by Peter Lodahl, Sparrow Quantum operates as a technology company focused on developing and commercializing advanced quantum computing solutions. In April 2025, Sparrow Quantum Aps raised EUR 21. 5 million in series A funding led by new investor PensionDanmark, with participation from other new investors Export and Investment Fund of Denmark and Novo Holdings. Other unspecified investors also participated in the round.

Sparrow Quantum offers light-matter interfaces for quantum technologies. The product is an on-chip single-photon source that can produce long strings of over 100 single photons without quality degrading and at a rate of more than 20 million single photons per second in fiber, which the customer can immediately deploy for experiments like multi-photon quantum simulations or quantum key distribution. The business also provides access to crucial building blocks for scaling up cutting-edge quantum technology applications in information processing and communication to researchers and developers of quantum technology systems. Application areas include secure quantum communication, photonic quantum computing, and quantum repeaters for the quantum internet.

The company will use the April 2025 funding to expand manufacturing, further research and development, and market its photonic quantum chip technology.
