Manipulation of phonon states in ion traps by shortcuts to adiabaticity

Shortcuts to adiabaticity (STA) provides the possibility of high accuracy manipulation of phonon states in ion traps. We propose a scheme realized experimentally for manipulating phonon states using STA and confirmed its effectiveness through generating Fock states. Our results show that the duration of the STA manipulation of phonon states is 16 times faster than that of the adiabatic evolution, and the non-resonant excitation can be suppressed by laser bias frequency, which are confirmed by experimental results. Moreover, we also carried out an experimental research on the robustness of STA, showing good robustness respect to the pulse shape deformation, bias noises and stochastic noise. This might lead to a useful step toward realizing fast and noise-resistant quantum manipulation within current experimental capacity.

Automated summary

In this study, we propose a scheme for manipulating phonon states using shortcuts to adiabaticity (STA) in ion traps. We experimentally demonstrate the effectiveness of this scheme by generating Fock states. Our results show that the STA manipulation of phonon states is 16 times faster than adiabatic evolution, and non-resonant excitation can be suppressed by laser bias frequency, which is confirmed by experimental results. Additionally, we investigate the robustness of STA and find that it is resilient to pulse shape deformation, bias noises, and stochastic noise.
