Superconducting diodes, characterized by nonreciprocal supercurrent transport, offer transformative
opportunities for ultra-low-power circuits. However, achieving reliable operation at temperatures
above liquid nitrogen remains a major challenge, limiting their practical applicability. Here, we
present a scalable strategy for high-temperature superconducting diodes based on intrinsic Josephson
junctions naturally present in a cuprate superconductor. We demonstrate that strong nonreciprocity
arises not only from broken spatial and time-reversal symmetries, but also from enhanced
anharmonicity in the current-phase relation, enabled by the atomically thin barrier of the intrinsic
junction. The diode efficiency strongly depends on the number of stacked intrinsic junctions, with
values exceeding 40% in single-junction devices. Notably, these high-temperature superconducting
diodes are readily scalable to large arrays, marking a critical step toward practical implementation in
energy-efficient computing architectures.
