论文摘要

DARTWARS（带有波动波放大器的检测器阵列读数）是一个三年的项目，旨在为低温检测器和量子读数（C-Band）开发高性能创新的创新波动参数放大器（TWPA）。实际发展遵循两种不同的有前途的方法，一种基于约瑟夫森连接（TWJPA），另一个基于一种基于高抗性超导体（KITWPA）的动力学电感。本文介绍了Dartwars合作的进步，以制作KitWPA的第一个工作原型。

DARTWARS (Detector Array Readout with Traveling Wave AmplifieRS) is a three years project that aims to develop high-performing innovative Traveling Wave Parametric Amplifiers (TWPAs) for low temperature detectors and qubit readout (C-band). The practical development follows two different promising approaches, one based on the Josephson junctions (TWJPA) and the other one based on the kinetic inductance of a high-resistivity superconductor (KITWPA). This paper presents the advancements made by the DARTWARS collaboration to produce a first working prototype of a KITWPA.
