Abstract: Quantum dynamics of an undamped single-well Duffing oscillator in presence of a monochromatic external field has been studied using a quantum theory of motion (QTM) as developed by de Broglie and Bohm. A phase space distance function between two initially close Bohmian trajectories and the associated Kolmogorov- Sinai entropy and the phase space volume clearly differentiate the quantum analogues of the corresponding regular and chaotic motions in the classical domain.
