Fast bias inversion of a double well without residual particle excitation
S. Martínez-Garaot, M. Palmero, D. Guéry-Odelin +1
We design fast bias inversions of an asymmetric double well so that the lowest states in each well remain so and free from residual motional excitation. This cannot be done adiabat…
Fast separation of two trapped ions
M. Palmero, S. Martínez-Garaot, U. G. Poschinger +2
We design fast protocols to separate or recombine two ions in a segmented Paul trap. By inverse engineering the time evolution of the trapping potential composed of a harmonic and…
Fast expansions and compressions of trapped-ion chains
M. Palmero, S. Martínez-Garaot, J. Alonso +2
We investigate the dynamics under diabatic expansions/compressions of linear ion chains.Combining a dynamical normal-mode harmonic approximation with the invariant-based inverse-en…
