我们设计了由强无序超导体制成的超级电感器，用于“混合”超导量子电路。超级电感器是由粒状铝膜制成的曲折纳米线。优化的设备的几何形状，使实现具有约1 μ H的电感和超过3 GHz的自谐振频率的超级电感器。这些紧凑的超级电感器对于从用于量子计算的超导电路到低温参量放大器和动力学电感光子探测器的微波元件的广泛应用是有吸引力的。
We design superinductors made of strongly disordered superconductors for implementation in "hybrid" superconducting quantum circuits. The superinductors are fabricated as meandered nanowires made from granular aluminum films. Optimization of the device geometry enables the realization of superinductors with an inductance of approximately 1 mu H and a self-resonance frequency of over 3 GHz. These compact superinductors are attractive for a wide range of applications, from superconducting circuits for quantum computing to microwave elements of cryogenic parametric amplifiers and kinetic inductance photon detectors.
