QDEVIL APS

Their core work

QDevil APS is a Danish deep-tech SME that designs and manufactures specialized auxiliary electronics for quantum computing research — the supporting hardware that quantum processors depend on but that mainstream suppliers do not provide. Their core product is optimized electronic control and filtering systems that operate alongside quantum computing hardware, particularly in cryogenic environments. They went from concept validation to full commercial development within two years, progressing through the EU SME Instrument phases with a single focused product line. Their customers are quantum computing research labs and hardware developers who need precision low-noise electronics matched to the extreme requirements of quantum systems.

What they specialise in

How they've shifted over time

QDevil's H2020 record is narrow but coherent: both projects address the exact same problem — auxiliary electronics for quantum computing — at different stages of maturity. The 2019 feasibility study validated the concept and market, and the 2020–2022 project scaled it into a full development effort. There is no observable shift in topic or technology direction; instead, the evolution is one of depth and investment, not breadth. This suggests a company that identified a very specific gap in the quantum hardware supply chain and committed fully to filling it.

QDevil is deepening into a narrow but fast-growing niche — quantum computing hardware infrastructure — and their trajectory points toward becoming a specialist supplier to the growing European quantum research ecosystem.

How they like to work

QDevil has acted exclusively as coordinator in both H2020 projects, which is consistent with the SME Instrument model where a single company drives its own product development. No consortium partners are recorded, meaning they have operated as a self-sufficient unit rather than as a networked collaborator. Anyone considering working with QDevil should expect to engage them as a supplier or technology partner rather than as a consortium co-developer with an established network to bring along.

QDevil's H2020 record shows no consortium partners and no cross-border collaborations, which is typical for SME Instrument solo grants. Their external network, if any, is not visible through EU project data and would need to be assessed through commercial and research customer relationships.

What sets them apart

QDevil occupies a very specific position in the quantum computing supply chain: they build the auxiliary electronics — the unglamorous but essential hardware — that quantum processors require and that standard electronics suppliers do not offer. In a field where most companies focus on qubits, algorithms, or systems integration, QDevil's focus on the surrounding hardware infrastructure makes them a rare and targeted supplier. For any research group or company building quantum hardware in Europe, QDevil represents a local, EU-funded specialist with a validated product line.

Highlights from their portfolio

• QCAUX
  The flagship project with €977k in EU funding marks QDevil's full commercial development push for their quantum computing auxiliary electronics — one of the larger single-SME grants in the quantum hardware space.
• QCAux
  The €50k Phase 1 feasibility study that validated QDevil's market case and unlocked the larger Phase 2 grant, demonstrating a disciplined two-stage commercialisation approach.
