Abstract
⺠In terms of quantum Fisher information, an inequality was established. ⺠It detects entangled states which are useful for sub-shot-noise sensitivity. ⺠In our work, we study the dynamics of an Ising model. ⺠Except for the periodic points, the evolution states satisfy the inequality. ⺠Thus an Ising model can effectively improve phase estimation sensitivity.
