## Abstract

Quantum states extended over a large volume in phase space have oscillations from quantum interferences in their Wigner distribution on scales smaller than $\\hbar$ [W.H. Zurek, Nature {\\bf 412}, 712 (2001)]. We investigate the influence of those sub-Planck scale structures on the sensitivity to an external perturbation of the state\'s time evolution. While we do find an accelerated decay of the ...
