Can superconducting wires simulate curved spacetime?

Researchers designed stacked arrays of superconducting wires that emulate curved geometries by assigning quantum phases to each wire and coupling them via Josephson junctions. The scheme reproduces hyperbolic (negative-curvature) spaces and lets them measure how disorder scrambles the boundary-to-bulk correspondence predicted by holography. The effect persists even under strong disorder, suggesting the principle is robust.
