Inverse engineering of fast state transfer among coupled oscillators
Xiao-Jing Lu, Ion Lizuain, J. G. Muga
We design faster-than-adiabatic state transfers (switching of quantum numbers) in time-dependent coupled-oscillator Hamiltonians. The manipulation to drive the process is found usi…
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…
Fast shuttling of a trapped ion in the presence of noise
Xiao-Jing Lu, J. G. Muga, Xi Chen +3
We theoretically investigate the motional excitation of a single ion caused by spring-constant and position uctuations of a harmonic trap during trap shuttling processes. A detaile…
Fast transitionless expansions of Gaussian anharmonic traps for cold atoms: bang-singular-bang control
Xiao-Jing Lu, Xi Chen, J. Alonso +1
Combining invariant-based inverse engineering, perturbation theory, and Optimal Control Theory, we design fast, transitionless expansions of cold neutral atoms or ions in Gaussian…
Fast and robust population transfer in two-level quantum systems with dephasing noise and/or systematic frequency errors
Xiao-Jing Lu, Xi Chen, A. Ruschhaupt +3
We design, by invariant-based inverse engineering, driving fields that invert the population of a two-level atom in a given time, robustly with respect to dephasing noise and/or sy…
