Abstract We show that the two-axis countertwisting interaction squeezes a coherent spin state into three states of interest in quantum information, namely, the equally weighted superposition state, the state close to the twin-Fock state, and the state achieving the Heisenberg limit of optimal sensitivity defined by the Cramér-Rao inequality, in addition to the well-known Heisenberg-limited state of spin fluctuations.
