    "abstract": "We investigate quantum computation with neutral atoms in optical microtraps\nwhere the qubit is implemented in the motional states of the atoms, i.e., in\nthe two lowest vibrational states of each trap. The quantum gate operation is\nperformed by adiabatically approaching two traps and allowing tunneling and\ncold collisions to take place. We demonstrate the capability of this scheme to\nrealize a square-root of swap gate, and address the problem of double\noccupation and excitation to other unwanted states. We expand the two-particle\nwavefunction in an orthonormal basis and analyze quantum correlations\nthroughout the whole gate process. Fidelity of the gate operation is evaluated\nas a function of the degree of adiabaticity in moving the traps. Simulations\nare based on rubidium atoms in state-of-the-art optical microtraps with quantum\ngate realizations in the few tens of milliseconds duration range.",
