Single-Ensemble Multiparameter Squeezing with Qudits
Xiaoshui Lin, Chunlei Qu, Chong Zu +1
Conventional spin squeezing enhances a single sensing channel. Here, we show how internal qudit levels enable simultaneous multiparameter squeezing within one ensemble. In two-comp…

Spin squeezing with short-range spin-exchange interactions
Michael A. Perlin, Chunlei Qu, Ana Maria Rey
We investigate many-body spin squeezing dynamics in an XXZ model with interactions that fall off with distance as in and spatial dimensions. In stark contrast…
