Researchers Achieve 50% Superconducting Diode Effect Via Driving

Quantum ZeitgeistOctober 25, 20264 min read

A superconducting circuit can now exhibit a near fifty per cent difference between forward and reverse current flow, compared to ten per cent previously, all *without* relying on fixed magnets or inherent material properties. This advance achieves symmetry breaking via electrical control of a helical Shiba chain, generating what’s described as a synthetic gauge flux instead of conventional magnetism. The result offers new possibilities for designing more flexible superconducting devices by tuning and reversing this ‘diode effect’ on demand.

Controlling electrical current direction is fundamental to modern electronics; however, devices favouring flow in one direction, superconducting diodes, have long relied on external magnetic fields. A team from multiple Indian institutions and Bilkent University has now achieved this effect without magnets, using instead a carefully timed signal applied to a helical Shiba chain, a structure combining superconductivity with magnetism. This demonstrates a new method for creating the superconducting diode effect, where…
