The expectation value of a quantum system observable can be written as a sum over interfering pathway amplitudes. In this letter, we demonstrate for the first time adaptive manipulation of quantum pathways using the Hamiltonian Encoding-Observable Decoding (HE-OD) technique. The principles of HE-OD are illustrated for population transfer in atomic Rubidium using shaped femtosecond laser pulses. The ability to manipulate multiple pathway amplitudes is of fundamental importance in all quantum control applications.
