A laser can draw superconductivity at the nanoscale

Researchers from ICMAB-CSIC, the Politecnico di Milano and Université de Liège have adapted a direct laser writing technique that allows them to "draw" superconducting properties in a material. The result is a new way to locally program the behavior of a superconductor, tuning it from a fully superconducting state to an insulating one with extraordinary precision.
