    "abstract": "Optimal-control techniques and a fast-approach scheme are used to implement a\ncollisional control phase gate in a model of cold atoms in an optical lattice,\nsignificantly reducing the gate time as compared to adiabatic evolution while\nmaintaining high fidelity. New objective functionals are given for which\noptimal paths are obtained for evolution that yields a control-phase gate up to\nsingle-atom Rabi shifts. Furthermore, the fast-approach procedure is used to\ndesign a path to significantly increase the fidelity of non-adiabatic transport\nin a recent experiment. Also, the entanglement power of phase gates is\nquantified.",
