Abstract

Author(s): Feng Chen, Jun-Jie Chen, Ling-Na Wu, Yong-Chun Liu, and Li You Spin squeezing (SS) is a recognized resource for realizing measurement precision beyond the standard quantum limit $∝1/\sqrt{N}$. The rudimentary one-axis twisting (OAT) interaction can facilitate SS and has been realized in diverse experiments, but it cannot achieve extreme SS for precision at the ... [Phys. Rev.
