Caption
The ring-shaped devices, magnified on the computer screen in this image, allow researchers to measure how electricity flows between the symmetrical contacts and visualize if there is a buildup of quantum states across the contacts, behavior indicative of the non-Hermitian skin effect. Although the team built multiple rings, they used only one to develop their conductance matrix.
