Sparrow Quantum raises $32M to scale photonic quantum chip production
Danish photonic quantum chip developer Sparrow Quantum has closed its Series A round after raising €27.5 million (~$32 million), adding new investors including North Ventures, Scale Capital, Jacob Jakobsen Gruppen ApS, and LIFTT EuroInvest, the investment vehicle created by the European Investment Bank and LIFTT.
The company had previously announced €21 million in funding earlier this year to accelerate R&D, expand chip production, and support the commercial rollout of its quantum photonic devices.
Sparrow Quantum’s flagship product, Sparrow Core, is a 3 × 3-mm integrated photonic chip that provides deterministic single-photon generation for quantum computing and quantum communication applications. The chip is built from indium arsenide/gallium arsenide quantum dots embedded in photonic crystal waveguides, with each section engineered to emit highly coherent single photons at wavelengths between 920 and 980 nm. The company says the technology, developed from research by founder Peter Lodahl at the Niels Bohr Institute, is already being used by several European technology companies.
Last month Sparrow Quantum also introduced Sparrow Nest, a single-photon generator system based on the Sparrow Core chip and designed for integration into quantum computing platforms, secure networks, and research environments. The latest funding is expected to support the wider deployment of both products as demand for photonic quantum hardware continues to grow.
