Abstract

This paper introduces a method to quantitatively determine the various pathways taken by a quantum system ill going from the initial state to the fin al target. The mechanism is revealed by encoding a signal in the system Hamiltonian and decoding the resultant nonlinear distortion of the signal in the system time evolution operator , The relevant interfering pathways determined by this analysis give insight into the physical mechanisms operative during the evolution of the quantum system. The mechanism analysis tools reveal the roles of multiple interacting quantum pathways to maximally take advantage of constructive and destructive interference,
