About Sparrow Quantum
Copenhagen spin-out from the Niels Bohr Institute making Sparrow Core, an on-chip deterministic single-photon source from InAs/GaAs quantum dots for photonic quantum computing. It raised a 21.5 million euro Series A led by PensionDanmark in April 2025, later reported as 27.5 million euros.
Sparrow Quantum and is based in Copenhagen, Denmark. It is listed under Quantum Computing, Photonic Computing. Reported funding is EUR 27.5M Series A, 2025.

What Sparrow Quantum works on
Quantum Computing
A quantum computer is a machine that uses the rules of quantum physics to process information. Its basic unit is the qubit. A classical bit is either 0 or 1. A qubit can be in a superposition, a state that combines both, and its measured result is probabilistic.
Photonic Computing
Photonic computing uses light instead of electricity to carry or process information. Photons have no charge, so light in a waveguide does not cause the resistive heating that current in a wire does, though lasers and modulators still use power, and many wavelengths can share one waveguide. The industry has two quite different parts: moving data with light, and computing with light.
