Enhanced and Long-Lived Spin Squeezing in 2D Finite-Range Systems via Global Control Fields.

Spin squeezing is both a fundamental witness of quantum entanglement and a key resource for quantum-enhanced metrology. While all-to-all interactions provide a paradigmatic route to generate spin squeezing, many programmable quantum simulators naturally realize finite-range interactions that induce coupling between col...
