Photonic quantum chips provider Sparrow Quantum has closed its series A round after raising €27.5 million (~$32 million). The Danish company’s latest investors include Denmark-based North Ventures, Scale Capital, and Jacob Jakobsen Gruppen ApS, as well as LIFTT EuroInvest, the investment vehicle created by the European Investment Bank and LIFTT, the Italian Venture Capital. The company previously announced it had raised €21 million earlier this year, saying at the time that the investment would help accelerate R&D efforts, expand chip production, and bring its quantum chips to market. Sparrow Quantum’s flagship product, Sparrow Core, is currently seeing use by several technology companies in Europe, the company said. Sparrow Core is an on-chip deterministic single-photon source aimed to help scale photonic quantum computing by generating photons reliably on demand. The foundation of the technology stems from research conducted by founder Peter Lodahl at the Niels Bohr Institute in Copenhagen. The integrated 3 × 3-mm chip is made from indium arsenide/gallium arsenide quantum dot structures embedded in photonic crystal waveguides. The chip is sectioned into an array of structures engineered for emitting highly coherent single photons at specific wavelengths between 920 and 980 nm. Additionally, the company released its Sparrow Nest single photon generator solution last month. The system uses Sparrow Core technology and is designed for integration into quantum computing, secure communication, and quantum research environments.
