FrostByte secures €1.3m to scale quantum computing cryogenic electronics

The Delft startup, a TU Delft and QuTech spin-off founded in 2025, raised the money from InnovationQuarter Capital, Graduate Ventures, Paeonia Group, UNIIQ and an angel investor.
It plans to expand its team, scale production of cryogenic switches and develop integrated cryo-CMOS chips for next-generation quantum systems; the deal is Graduate Ventures' 80th investment.
FrostByte says its technology moves control electronics into dilution refrigerators, aiming to cut cabling, heat and complexity that hinder scaling quantum computers to millions of qubits.
As competitors announce commercial products, can FrostByte's technology win the race to control millions of qubits?
With control electronics moving inside the cryostat, are we creating the first truly integrated quantum processing units?
In 2025, FrostByte spun out of TU Delft's QuTech and secured €1.3 million in funding to expand its team, scale cryogenic switch production, and advance its cryo-CMOS chip research. This innovative technology moves quantum control electronics inside the cryogenic environment at 4K, drastically reducing wiring complexity, heat leakage, and signal errors that currently limit quantum computer scaling. FrostByte developed accurate cryogenic transistor models, cryo-optimized circuits, and advanced thermal management, validating their approach with large chip prototypes that minimally impact qubit performance. Supported by ongoing collaborations, FrostByte plans pilot deployments in the late 2020s, aiming to enable scalable quantum computers with millions of qubits.
