  We extract the information of a quantum motion and decode it into a certain
orbit via a single measurable quantity. Such that a quantum chaotic system can
be reconstructed as a chaotic attractor. Two configurations for reconstructing
this certain orbit are illustrated, which interpret quantum chaotic motions
from the perspectives of probabilistic nature and the uncertainty principle,
respectively. We further present a strategy to import classical chaos to a
quantum system, revealing a connection between the classical and quantum
worlds.
