FrostByte develops cryo-electronics intended to operate at extremely low temperatures for quantum technologies, including specialized cryo-CMOS circuits. The company also produces cryogenic integrated circuits and switches to control, bias and read out quantum devices locally. Its approach emphasizes scalability by moving control infrastructure closer to the processor to reduce external cabling, heat generation and system complexity for large-scale qubit systems. FrostByte was founded by James Kroll (CEO) and Luc Enthoven (CTO) with scientific support from Fabio Sebastiano and Masoud Babaie. The company is based in Delft, the Netherlands and recently raised €1.3M to expand operations and development efforts.
