Superconducting technology represents a rapidly advancing field and applications of the technology have been demonstrated by tech giants such as Google with their recent 53-qubit quantum computer. Currently, much of the signal detection of quantum resonators is carried out at cryogenic temperatures, while readout electronics and signal processing is carried out at lab temperatures. This requires individual cables for each component introducing an increased thermal load as complexity increases, representing a major roadblock in the complexity of quantum devices that can be achieved with such a readout scheme.By implementing control and readout circuits within the cryogenic stage; the size of resonator array that can be addressed and controlled will be exponentially increased. The ability to build resonator arrays with thousands of components is crucial for the advancement of superconducting technologies; allowing for dramatic improvements in processing power and computing speeds in quantum computers as well as the upscaling of superconducting single photon detector arrays for implementation in quantum-secure communications and LIDAR systems.

超导技术代表了一个快速发展的领域，谷歌等科技巨头已经通过其最新的 53 量子位量子计算机展示了该技术的应用。目前，量子谐振器的大部分信号检测都是在低温下进行的，而读出电子设备和信号处理则是在实验室温度下进行的。这需要每个组件的单独电缆随着复杂性的增加而引入增加的热负载，这代表了通过这种读出方案可以实现的量子器件的复杂性的主要障碍。可寻址和控制的谐振器阵列的尺寸将呈指数级增加。构建具有数千个组件的谐振器阵列的能力对于超导技术的进步至关重要；可以显着提高量子计算机的处理能力和计算速度，以及升级超导单光子探测器阵列，以在量子安全通信和激光雷达系统中实现。
