Query: A lower bound of quantum conditional mutual information   In this paper, a lower bound of quantum conditional mutual information is
obtained by employing the Peierls-Bogoliubov inequality and Golden Thompson
inequality. Comparison with the bounds obtained by other researchers indicates
that our result is independent of any measurements. It may give some new
insights over squashed entanglement and perturbations of Markov chain states.
