Noise Sensitivities for an Atom Shuttled by a Moving Optical Lattice via Shortcuts to Adiabaticity
Xiao-Jing Lu, Andreas Ruschhaupt, Sofía Martínez-Garaot +1
We find the noise sensitivities (i.e., the quadratic terms of the energy with respect to the perturbation of the noise) of a particle shuttled by an optical lattice that moves acco…

Fast shuttling of a particle under weak spring-constant noise of the moving trap
Xiao-Jing Lu, A. Ruschhaupt, J. G. Muga
We investigate the excitation of a quantum particle shuttled in a harmonic trap with weak springconstant colored noise. The Ornstein-Uhlenbeck model for the noise correlation funct…

Optimal transport of two ions under slow spring-constant drifts
Xiao-Jing Lu, Mikel Palmero, Andreas Ruschhaupt +2
We investigate the effect of slow spring-constant drifts of the trap used to shuttle two ions of different mass. We design transport protocols to suppress or mitigate the final exc…
