Generation of scalable many-body Bell correlations in spin chains with short-range two-body interactions
Dynamical generation of strong and scalable quantum resources, like many-body entanglement and Bell correlations, in spin-1/2 chains is possible with all-to-all interactions, either for constant interaction strength realizing one-axis twisting protocol or for power-law decaying potentials. We show, however, that such quantum resources can also be dynamically generated with a finite range of interactions. We identify a threshold range and indicate a threshold time when scalable quantum correlations appear. Finally, we show that the certification of generated states is accessible in modern quantum simulator platforms.
