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) and 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,” — 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.”
