Quantum foundry · Gothenburg and Copenhagen

Superconducting quantum devices, fabricated to spec.

We fabricate your designs in the Chalmers and DTU cleanrooms, on a schedule you can book, with published performance data for our process.

What do you need to do?

Measured, not adjectives

Every number comes with a date.

We publish what we measure: reference devices, averages, the best result, and the date and datasheet behind each one. If a number isn't in a published, dated source, it isn't on this site.

  • QiB0Reference device CS_QIB0_30: T1 of 138, 121, 132 and 109 µs across its four qubits.
  • Q-MPWProcess: ±20% junction-resistance variation across the wafer, ±10% within a block, published before you submit.
  • 2024Three peer-reviewed papers by our engineers on loss mechanisms in aluminium-on-silicon qubits and resonators (npj Quantum Information, Physical Review Applied, APL Quantum).

Your design stays yours

We sign an NDA before you send a single file. Only your team and our foundry see your design. Wafer previews show your chips and nothing else, and design data is handled on a need-to-know basis.

Shipping and export control

Our quantum devices are EU dual-use items (category 3A001). Every order needs a signed End-User Statement before shipping. Within the EU, and to Australia, Canada, Iceland, Japan, Liechtenstein, New Zealand, Norway, Switzerland, the UK and the US, no individual licence is needed. Anywhere else needs an export licence, which adds time, so tell us your destination early and we'll start the paperwork with you.

Two cleanrooms, one team

Gothenburg and Copenhagen.

We work in Chalmers MC2 and DTU Nanolab — together more than 10,000 m² of cleanroom and over 2,000 instruments. You get that tooling without paying for our fab. Our Danish team at DTU Science Park works with customers across Denmark and the Nordics.

People

Built by cleanroom scientists.

Many of us came from Chalmers — from its quantum technology lab and from MC2, where one of us made detectors for ESA missions including Herschel and JUICE.
