New superconducting diode gives greater control over the flow of electrons

Researchers have created a new superconducting diode based on two-dimensional oxide interfaces, according to Physics World. What's novel here is the ability to edit or reconfigure the device using atomic force microscope lithography—essentially using a microscopic probe to reshape how electrons flow through the material. Superconducting diodes are famously hard to control, so this fine-grained editability is a significant win for quantum computing and next-generation electronics.
