Sparrow Quantum, a leading European supplier of photonic quantum chips, has secured €21.5 million in Series A funding to accelerate the development and commercialization of its world-leading quantum chip technology. The investment round was led by PensionDanmark, with strong backing from EIFO and Novo Holdings and additional investments from existing investors 2xN, LIFTT, and the European Innovation Council. This investment will enable Sparrow Quantum to meet the growing demand for photonic quantum hardware by accelerating R&D, expanding chip production, and bringing next-generation quantum chips to market.
Sparrow Quantum builds on a rich Danish history of scientific quantum discovery. While at the Niels Bohr Institute in Copenhagen, its founder Professor Peter Lodahl conducted research that laid the groundwork for the company’s flagship product, Sparrow Core — an on-chip deterministic single-photon source critical for scaling photonic quantum computing by generating photons reliably on demand. Today, Sparrow Core sets the industry benchmark, delivering best-in-class efficiency, quality, and exceptional stability.
“With this investment, we can truly intensify our efforts to bring quantum technology from the lab to the market,” says Professor Peter Lodahl, Founder and Chief Quantum Officer of Sparrow Quantum. “It enables us to scale up in three critical areas which are essential for industrializing our photonic quantum chips and ensuring we can deliver stable, advanced solutions to the market. It is an honor to build up a truly world-class team of quantum photonics experts with unique know-how on quantum photonic chip technology”.
Building on a €4.1 million seed round raised in 2023, the new €21.5 million funding will allow Sparrow Quantum to expand its operations across several strategic areas. The company plans to scale up production of its photonic quantum chips to meet increasing market demand, advance research and development efforts with a focus on entangled photon sources, and grow its technical team to support the development and delivery of new quantum products.
“Quantum technology can open an entirely new world of solutions to complex problems, and the Danish research environment, from which Sparrow Quantum emerges, has the potential to position Denmark as an international frontrunner in the field. Therefore, we see a clear potential for the investment to yield an attractive return on our members’ pension savings while also benefiting the national economy and Danish industry. That is why it is an obvious investment for PensionDanmark,” says Peter Stensgaard Mørch, CEO of PensionDanmark.
In the past few years, Sparrow Quantum has made significant strides toward delivering market-ready solutions by partnering with quantum computer integrators and full-stack system providers across Europe. Powered by the Sparrow Core chip, photonic quantum computers can achieve notably faster processing speeds than earlier iterations using probabilistic sources, fuelling further advancements in generative AI and quantum-optimized machine learning. These developments promise unprecedented scalability and real-world applications across multiple sectors — within Europe and beyond.
This investment exemplifies how to foster broader collaboration among chip manufacturers, foundries, and system integrators on European soil, marking a crucial leap for Europe’s emerging quantum supply chain. As Sparrow Quantum’s CEO Kurt Stokbro highlights:
“This investment is a testament to Denmark and Europe’s ability to lead in quantum technology. With strong backing from visionary Danish investors, we are ready to unlock quantum breakthroughs that benefit society and the global economy.”
Beyond commercial scaling, this investment strengthens Europe’s quantum supply chain, ensuring that chip manufacturing, quality control, and R&D remain within European borders. This aligns with key EU initiatives like the Chips Act, reinforcing technological sovereignty and global competitiveness in quantum innovation.
“Sparrow Quantum demonstrates how Denmark – building on the foundation of the Niels Bohr Institute – has developed world-leading quantum expertise. Professor Lodahl’s research paved the way for the company’s groundbreaking quantum chip, which is now in global demand. With our investment, we are strengthening both their leading position and the role of Denmark and Europe in the quantum future,” says Peder Lundquist, CEO of EIFO.
Photonic quantum technology uses light particles (photons) instead of electrons or atoms to power quantum computers and secure communication systems. Unlike classical bits, quantum bits—or qubits—can exist in multiple states simultaneously, enabling much faster problem-solving. Photonic systems offer advantages such as room-temperature operation, noise resistance, and easy integration into microchips. A crucial component is the deterministic single-photon source, which emits one photon at a time to ensure stable and reliable quantum operations.
