Gap-Protected Heisenberg-Limited Squeezing with Locally Interacting Multi-Level Spins
Sakshi Bahamnia, Sagar Chaudhary, Arman Duha +1
We demonstrate a general mechanism to generate scalable, metrologically useful entanglement in the form of generalized spin squeezing in multi-level (qudit) spin systems with power…

Universal Spin Squeezing Dynamical Phase Transitions across Lattice Geometries, Dimensions, and Microscopic Couplings
Arman Duha, Thomas Bilitewski
Recent work has identified a dynamical squeezing phase transition in power-law interacting bilayer XXZ spin models, separating a fully collective phase with Heisenberg-limited sque…
