Gap-Protected Heisenberg-Limited Squeezing with Locally Interacting Multi-Level Spins
Published in arXiv preprint, 2026
We study how local exchange interactions protect collective dynamics in multilevel spin systems, enabling scalable squeezing beyond all-to-all connectivity. Analytical excitation spectra and numerical dynamics reveal a route to useful qudit entanglement.
