QET Sweden
QET Sweden develops low-noise microwave amplifiers for measuring quantum devices. Vidar targets the weak-signal readout chain rather than quantum processing itself. Chalmers also identifies the company as Quantum Enabling Technologies.

What it does. Where it fits.
Traveling-wave parametric amplifiers and associated control electronics for quantum readout.
Who should look closer
Editorial inference: Cryogenic quantum teams evaluating amplifier integration and readout-noise requirements.
QubitWire’s editorial assessment of practical fit.Amplifier quotation and technical enquiry
The official company site offers quotation requests and describes Vidar collaboration with SCALINQ. Confirm model availability, packaging, operating conditions and integration support directly.
Check the current access route ↗What has been demonstrated
A Vinnova-hosted project outcome says Vidar was commercialized and sold, while Mimir control electronics reached a functional prototype. The agency identifies QET Sweden AB as coordinator but says participants supplied the outcome narrative.
What remains unresolved
Treat commercialization outcomes as project-reported. A functional controller prototype is distinct from a commercial system, and amplifier specifications do not establish processor performance.
The next question to watch
Which current model datasheets and external installation results show gain, added noise, bandwidth and stability together?
A research question, not a promised milestone.QubitWire coverage
