摘要

超导电子学在节能经典计算和量子计算应用的发展中具有重要意义。这种系统需要非互易超导电路元件，如超导二极管，但在超导电路中集成多个超导二极管仍然是一个挑战。在这里，我们报道了一个超导二极管桥，它由多个超导二极管组成，具有可重复的特性和几个开尔文的工作温度。超导二极管由单质超导体钒和绝缘铁磁体硫化铕的薄膜双层制成。四个几乎完全相同的二极管在相同的超导薄膜上形成超导二极管桥。该桥可以作为一个全波整流器，效率高达42±5%，并提供交流（交流）到直流（直流）信号转换能力，频率高达40 kHz。

Efficient superconducting diodes and rectifiers for quantum circuitry

Superconducting electronics is of use in the development of energy-efficient classical and quantum computing applications. Non-reciprocal superconducting circuit elements, such as superconducting diodes, are needed for such systems, but integrating several superconducting diodes in a superconducting circuit remains a challenge. Here we report a superconducting diode bridge that consists of multiple superconducting diodes with reproducible characteristics and operating temperatures of a few Kelvin. The superconducting diodes are fabricated from thin-film bilayers of the elemental superconductor vanadium and the insulating ferromagnet europium sulfide. Four practically identical diodes are patterned on the same superconducting film to create the superconducting diode bridge. The bridge can function as a full-wave rectifier with an efficiency up to 42 ± 5%, and offers alternating current (a.c.) to direct current (d.c.) signal conversion capabilities at frequencies up to 40 kHz.
