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…

Scalable spin-nematic squeezing in multi-level dipole-interacting Rydberg atom arrays
Sakshi Bahamnia, Thomas Bilitewski
We study the generation of metrologically useful entanglement in a three-level (spin-1) system naturally realized in arrays of dipole-interacting Rydberg atoms confined in optical…
