One-way superconducting diode has massive implications for electronics
A TU Delft team has demonstrated a one-way superconductor that gives zero resistance in one direction, but blocks current completely in the other. The discovery, long thought impossible, heralds a 400x leap in computing speed and huge energy savings.Superconductors can make electronic devices hundreds of times faster, and completely eliminate energy loss, but they've only been useful for certain applications, since it's been impossible to prevent them from conducting in all directions without the use of magnetic fields.…
