Extreme Spin Squeezing from Deep Reinforcement Learning

27 Sep 2019 Chen Feng Chen Jun-Jie Wu Ling-Na Liu Yong-Chun You Li

Spin squeezing (SS) is a recognized resource for realizing measurement precision beyond the standard quantum limit $\propto 1/\sqrt{N}$. 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 Heisenberg limit $\propto 1/{N}$...
