论文摘要
我们提出了在约瑟夫森连接的通量偏置超导电路中实现超导二极管效应的实现。到目前为止，对超导二极管效应的观察仅限于相当异国的材料平台。在理论提案中，它依赖于约瑟夫森连接的当前相位关系的非鼻腔形式。在这里，我们展示了如何在没有任何此类要求的情况下在超导电路中设计二极管效应。唯一必要的成分是标准的正弦约瑟夫森连接和通量偏置线，它们在基于可扩展的工业硅芯片超导设计过程中很容易获得。
We propose a realization of the superconducting diode effect in flux biased superconducting circuits of Josephson junctions. So far the observation of the superconducting diode effect has been limited to rather exotic material platforms. In theoretical proposals, it relied on a non-sinusoidal form of the current phase relation of Josephson junctions. Here, we show how the diode effect can be engineered in superconducting circuits without any such requirements. The only necessary ingredients are standard sinusoidal Josephson junctions and flux bias lines that are readily available in scalable industrial silicon-chip based superconducting design processes.
