Dutch quantum computing component firm FrostByte has secured new funding to develop supercooled electronics.

The company this week closed a €1.3 million ($1.5m) pre-seed funding round, with backing from UNIIQ, Paeonia Group, InnovationQuarter, Graduate Ventures, and an angel investor.

A spin-off from TU Delft and QuTech, FrostByte aims to develop cryo-CMOS technology that brings control electronics closer to the quantum processor, reducing the amount of cables and electronics.

“With this investment, we can further develop our technology towards manufacturable cryo-electronics for the global quantum industry,” said James Kroll, CEO and co-founder of FrostByte.

Aside from the quantum processing units themselves, most parts of supercooled quantum computers operate at room temperature in racks next to dilution refrigerators.

FrostByte’s first products are a family of cryogenic RF switches that replace room-temperature switching with smaller, low-power components operating down to millikelvin temperatures.

“FrostByte is exactly the kind of company that shows what the Dutch knowledge economy is capable of producing,” said Auke van den Hout, managing partner at Graduate Ventures.

“This investment fits within Graduate Ventures’ broader strategy of backing key technologies such as quantum, AI, and climate tech, where fundamental research is translated directly into industrial application.”
