SCALINQ and QET Sweden Introduce Dual TWPA Options for Quantum Computing
Mohamed Abdel-Kareem2025-03-18T16:58:13-07:00SCALINQ, a provider of quantum computing hardware, and QET Sweden, a spin-out from Chalmers University of Technology, have launched the QET Vidar Traveling-Wave Parametric Amplifiers (TWPAs) at the APS March Meeting 2025. The amplifiers are available in two configurations: Model S (single TWPA) and Model D (double TWPA). Both models feature an uninterrupted 4 GHz gain bandwidth, advanced flux biasing, and electrostatic discharge (ESD) protection, addressing key challenges in quantum measurement such as signal fidelity and system stability. The QET Vidar TWPAs leverage patented multi-TWPA integration technology, enabling the combination of multiple amplifiers in a single enclosure. This design reduces space requirements and simplifies system setup while maintaining low noise performance. [...]
