Programmable superconducting diode can flow on command

A team of researchers led by the University of Pittsburgh demonstrated a programmable superconducting diode at the LaAlO3/KTaO3 (LAO/KTO) interface, an advance that holds potential to enhance/help usher in the future of next-generation electronics and quantum circuits. The work, published in the journal Nano Letters, and featured on the journal's cover, was led by first author Muqing Yu, a graduate student in the lab of Jeremy Levy, Distinguished Professor of Condensed Matter Physics.
