Fig. 4: Experimental SR-entanglement detection in a trapped ion quantum simulator using data obtained in ref. 28.
From: Symmetry-resolved entanglement detection using partial transpose moments
For a total system of N = 10 spins and subsystem A, B = [4, 5], [6, 7], we present in a) the SR-D2 ratio and b) SR-p3-PPT ratio as a function of time for various symmetry sectors . In both panels, entanglement is detected in regimes where the corresponding global conditions do not reveal entanglement, as indicated in the shaded grey areas (values below unity). The points with error bars correspond to the values and uncertainties extracted from the experimental data from ref. 28, whereas the dashed (solid) lines are theoretical simulations of unitary dynamics (taking decoherence effects into account), as detailed in refs. 28,34.
