Superconductivity is an advantageous property observed in some materials, which entails an electrical resistance of zero at extremely low temperatures. Superconductors, materials that exhibit this property, have proved to be highly promising for the development of various electronic components for both classical and quantum technologies.

Researchers at Massachusetts Institute of Technology (MIT), University of California–Riverside and SEEQC Inc. recently introduced a new system comprised of four superconducting diodes (SDs), which are electronic devices that allow electric current to flow in only one direction and are made of superconducting materials.

Their superconducting diode bridge, introduced in a paper published in Nature Electronics, was found to perform remarkably well at cryogenic temperatures, achieving rectification efficiencies as high as 42% ± 5%.
