The conductance $g$ behaves as $g \\sim exp(-L/l)$ with system size $L$ and localization length $l$ in the strong disorder limit. However, classical systems can always have metallic states in which Ohm's law shows a constant $g$ in $d=2$. We study a two-dimensional quantum percolation model by controlling dephasing effects. The numerical investigation of $g$ aims at simulating a quantum-to-classical percolation evolution. An unexp","authors_text":"Chui-Zhen Chen, Haiwen Liu, Hua Jiang, Junjie Qi, X.C.
