SCALINQ and QET Sweden Announce Groundbreaking Dual TWPA Option for Quantum Computing

March 17, 2025 – Anaheim, CA
QET Sweden, a pioneering spin-out from Chalmers University of Technology, together with
SCALINQ, a rapidly growing provider of quantum computing hardware, proudly announces
the launch of the QET Vidar Traveling-Wave Parametric Amplifiers at the APS March
Meeting 2025. These state-of-the-art amplifiers come in two models, Model D (double
TWPA) or Model S (Single TWPA), both designed to deliver unprecedented gain bandwidth,
minimal pump interference, and superior noise performance for quantum computing
applications.


Developed under the leadership of Professor Per Delsing, co-founder and CSO of QET,
QET’s TWPAs build on decades of superconducting circuits research at Chalmers. The
products offer a 4 GHz uninterrupted gain bandwidth, nearly twice as large as many
competing designs, and integrate patented solutions that simplify system setup while
protecting against external magnetic fields and ESD events.


“This product is a major step toward next-generation quantum computation,”
says Zaid Saaed, CEO of SCALINQ. “By collaborating with QET, we’re bringing
researchers and quantum hardware developers a unique and optimized
combination of wide bandwidth, low noise, and straightforward integration.”

Key Features and Benefits

Uninterrupted 4 GHz Gain Bandwidth
Delivers exceptional performance for measuring qubits, doubling the bandwidth of
many existing TWPAs.

Minimal Pump Interference
With the pump set outside the signal band, interference is reduced and filtering
becomes much simpler.

Patented Multi-TWPA Integration
Patented technology enables multiple amplifiers to be combined in a single
enclosure, saving space and reducing total cost.

Advanced Flux Biasing & ESD Protection
A homogeneous magnetic field improves stability and performance, while built-in
ESD safeguards extend product longevity.

Product Models

QET Vidar Model S
A single-amplifier solution offering large bandwidth and very low noise.

QET Vidar Model D
Integrates two TWPAs into a single box, providing a cost-effective, space-saving
solution.

“When you measure qubits, you want large bandwidth, very low noise, and
minimal pump interference,” says Professor Delsing.
“Our three-wave mixing TWPAs solve all these challenges at once, marking a
significant leap in quantum measurement technology.”
