“…One of the more feasible schemes is to expand bits numbers by coupling both the internal states and motional states of ions, which is also called phonon state manipulation in the ion trap [15][16][17][18][19]. Such scheme can be used to create entanglement between ions [20][21][22][23][24][25], to implement quantum gates [26][27][28][29], and to simulate the behavior of complex quantum systems [30][31][32]. Moreover, phonon modes have been engineered to realize different properties, such as localization, squeezing, and non-classicality [15,16,20].…”

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.
