Researchers find way to form diodes from superconductors

A group of researchers from Pisa, Jyväskylä, San Sebastian and MIT have demonstrated how a heterostructure consisting of superconductors and magnets can be used to create unidirectional current like that found in semiconductor diodes.

These novel superconductor diodes, however, operate at much than their semiconductor counterparts and are therefore useful in quantum technologies.
