FrostByte, a Delft-based startup growing cryogenic electronics options for quantum applied sciences, has raised €1.3 million in funding from InnovationQuarter Capital, Graduate Ventures, Paeonia Group, UNIIQ and an angel investor. With this funding, Graduate Ventures reaches a milestone, marking its eightieth funding
The corporate plans to make use of this capital to additional develop its workforce, scale manufacturing of cryogenic switches and develop built-in cryo-CMOS chips for the following era of quantum programs.
James Kroll, CEO and co-founder of FrostByte: “With this funding, we are able to additional develop our expertise in direction of manufacturable cryo-electronics for the worldwide quantum trade.”
Based in 2025, FrostByte is led by founders James Kroll (CEO) and Luc Enthoven (CTO), and is scientifically supported by Fabio Sebastiano and Masoud Babaie. Each advisors are pioneers in cryo-CMOS expertise with a long time of analysis expertise, now utilized commercially.
FrostByte is a spin-off from TU Delft and QuTech. It focuses on cryogenic built-in circuits (ICs) and specialised management electronics for quantum computing.
The corporate states that it addresses a key bottleneck in quantum computing. Earlier than quantum computer systems may be scaled up, a vital infrastructure concern must be resolved: managing tens of millions of qubits with out inflicting system overloads because of extreme cabling, warmth, and exterior electronics.
The Delft-based startup claims to be growing cryo-electronics that deal with precisely this problem. The corporate develops expertise that brings management infrastructure nearer to the quantum processor itself, laying the inspiration for a brand new era of scalable quantum programs.
“Quantum processors function at temperatures near absolute zero. In present programs, a big a part of the management electronics stays exterior the cryogenic surroundings, which means that each extra qubit results in extra connections, complexity and warmth era. FrostByte strikes a part of that management electronics into the dilution fridge itself, utilizing specialised cryo-CMOS expertise designed to function at extraordinarily low temperatures. In doing so, the corporate is growing a brand new era of cryogenic management electronics that make quantum programs extra compact, energy-efficient and scalable,” defined the corporate.
