  We improve the heavy quark potential, extracted from the Wilson loop average
in the Ads/CFT approach by taking the quantum fluctuation of the only radial
coordinate of $Ads_5$ which is transverse to the world-sheet of the classical
Nambu-Goto string in the static gauge, and obtain the universal
L{\"u}scher-Symanzik-Weisz/L{\"u}scher term.
