    "abstract": "We propose an implementation of the quantum fast Fourier transform algorithm\nin an entangled system of multilevel atoms. The Fourier transform occurs\nnaturally in the unitary time evolution of energy eigenstates and is used to\ndefine an alternate wave-packet basis for quantum information in the atom. A\nchange of basis from energy levels to wave packets amounts to a discrete\nquantum Fourier transform within each atom. The algorithm then reduces to a\nseries of conditional phase transforms between two entangled atoms in mixed\nenergy and wave-packet bases. We show how to implement such transforms using\nwave-packet control of the internal states of the ions in the linear ion-trap\nscheme for quantum computing.",
