Josephson parametric converter with impedance matching network

One or more systems, devices, and/or methods of use provided herein relate to a device that may provide bandwidth and/or saturation power to amplify multiple readout frequencies or convert one or more frequencies. In quantum technology, one or more systems, devices, and/or methods of use provided herein may be employed to read out multiple qubit resonators simultaneously. An apparatus may include a Josephson parametric converter apparatus including a Josephson ring modulator having a pair of nodes and an impedance matching circuit network operably connected across the pair of nodes. The device may operate separately in either an amplification mode or a conversion mode. 本文提供的一个或多个系统、装置和/或使用方法涉及一种装置，其可以提供带宽和/或饱和功率以放大多个读出频率或转换一个或多个频率。在量子技术中，可以采用本文提供的一个或多个系统、装置和/或使用方法来同时读出多个量子位谐振器。一种装置可以包括约瑟夫森参量转换器装置，该约瑟夫森参量转换器装置包括具有一对节点的约瑟夫森环形调制器以及跨该对节点可操作地连接的阻抗匹配电路网络。该装置可以在放大模式或转换模式下单独操作。
