    "abstract": "We describe a quantum computer based upon the coherent manipulation of\ntwo-level atoms between discrete one-dimensional momentum states. Combinations\nof short laser pulses with kinetic energy dependent free phase evolution can\nperform the logical invert, exchange, CNOT and Hadamard operations on any\nqubits in the binary representation of the momentum state, as well as\nconditional phase inversion. These allow a binary right-rotation, which halves\nthe momentum distribution in a single coherent process. Fields for the coherent\ncontrol of atomic momenta may thus be designed as quantum algorithms.",
