FrostByte Secures €1.3 Million to Solve the Quantum Computing Wiring Bottleneck
Delft, Sunday 10 May 2026
Dutch startup FrostByte has secured €1.3 million to develop microchips that operate near absolute zero, aiming to eliminate massive wiring bottlenecks and make large-scale quantum computers a commercial reality.
Addressing the Cabling Conundrum
The fundamental challenge in scaling quantum computers lies in the physical infrastructure required to manage delicate quantum bits, or qubits [GPT]. Currently, control electronics operate at room temperature and must be connected to the qubits—which reside in extreme cryogenic environments—via lengthy, complex cabling [5]. As the industry aims to scale from tens of qubits to millions, this architecture becomes increasingly untenable due to severe space constraints and excessive heat generation [2][5]. To resolve this, FrostByte, a spin-off from Delft University of Technology (TU Delft) and QuTech established in 2025 [3][5], has developed application-specific integrated circuits (ASICs) using cryo-CMOS technology [5]. These chips are designed to function directly within the cooling environment at temperatures of 4 Kelvin and below, placing the control mechanisms adjacent to the quantum processor [1][5].
Scaling Through Existing Semiconductor Supply Chains
FrostByte’s approach is particularly significant because its cryo-CMOS chips are designed to be manufactured using existing commercial semiconductor processes [5]. By plugging directly into established production infrastructures, the startup aligns itself with the robust semiconductor value chain heavily anchored in the Netherlands and the broader European Union [5][GPT]. The Dutch ecosystem is already a global powerhouse in semiconductor equipment manufacturing, led by industry giants such as ASML and ASM, alongside emerging hubs for integrated photonics like PhotonDelta [GPT]. Integrating quantum control chip design into this existing manufacturing paradigm ensures that quantum hardware can be scaled efficiently without requiring entirely new fabrication methodologies [alert: ‘Assuming current fabrication methods are fully sufficient for cryo-CMOS scaling based on standard commercial processes mentioned in source 5’].

The €1.3 million investment in FrostByte also marks a notable milestone for the regional venture capital landscape. For the early-stage investment firm Graduate Ventures, which was founded in 2021 by alumni of Erasmus University Rotterdam, Erasmus MC, and TU Delft, backing FrostByte represents its 80th portfolio investment in exactly five years [1][4]. This equates to an aggressive deployment pace, averaging 16 investments annually. The firm typically invests between €7
