FrostByte secures €1.3M to scale cryogenic quantum electronics

FrostByte banked €1.3M in a funding round featuring InnovationQuarter Capital, Graduate Ventures, Paeonia Group, UNIIQ and an unnamed angel investor. The investment marks the 80th deal for Graduate Ventures and provides the Delft-based startup with capital to scale its hardware production and expand its engineering team.

The company develops cryogenic integrated circuits (ICs) and specialised control electronics designed to operate at temperatures near absolute zero. By moving control infrastructure closer to the quantum processor, FrostByte aims to eliminate the "wiring bottleneck"—the heat and complexity generated when quantum systems are connected to room-temperature electronics via extensive cabling.

A spin-off from TU Delft and QuTech, FrostByte is led by co-founders James Kroll and Luc Enthoven. The startup's technical roadmap includes the development of integrated cryo-CMOS chips, which are necessary for managing the millions of qubits required for commercial-grade quantum computing. Scientific advisors Fabio Sebastiano and Masoud Babaie support the venture with research experience in cryogenic CMOS technology.

This raise highlights the continued strength of the Delft quantum cluster as European deep-tech investors shift focus toward the fundamental infrastructure required to make quantum systems scalable.
