Front Cover: Superconducting Diode Effect in a Constricted Nanowire (Adv. Quantum Technol. 9/2024)

Superconducting diodes with nonreciprocal transport effect enable constructing novel logic devices, thereby laying the cornerstone of contemporary integrated circuits technology beyond Josephson junction-based circuits. Xiaofu Zhang, Lixing You, and co-workers designed and fabricated novel superconducting diodes based on the minimal superconducting electrical component – the superconducting nanowire –, which can rectify both square-wave and sine-wave signals without distortion (see article number 2300378). The superconducting nanowire diodes are irrespective of specific superconducting materials, and therefore promising for constructing low-dissipation superconducting integrated circuits for novel computation architectures.
