Superconducting weak links in next generation ultrafast and low power electronics for control and readout of quantum resonators arrays

超导技术是一个快速发展的领域，谷歌等科技巨头最近用53量子位量子计算机展示了该技术的应用。目前，许多量子谐振器的信号检测是在低温下进行的，而读出电子和信号处理是在实验室温度下进行的。这需要每个组件单独的电缆，随着复杂性的增加，热负荷也会增加，这是使用这种读出方案实现量子设备复杂性的主要障碍。通过在低温阶段实施控制和读出电路；可寻址和控制的谐振器阵列的大小将呈指数级增长。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；允许量子计算机的处理能力和计算速度的显着提高，以及用于量子安全通信和激光雷达系统的超导单光子探测器阵列的升级。

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.
