Connection between inverse engineering and optimal control in shortcuts to adiabaticity
Qi Zhang, Xi Chen, David Guéry-Odelin
We consider fast high-fidelity quantum control by using a shortcut to adiabaticity (STA) technique and optimal control theory (OCT). Three specific examples, including expansion of…
Fast and robust control of two interacting spins
Xiao-Tong Yu, Qi Zhang, Yue Ban +1
Rapid preparation, manipulation, and correction of spin states with high fidelity are requisite for quantum information processing and quantum computing. In this paper, we propose…
Trigonometric protocols for shortcuts to adiabatic transport of cold atoms in anharmonic traps
Jing Li, Qi Zhang, Xi Chen
Shortcuts to adiabaticity have been proposed to speed up the "slow" adiabatic transport of an atom or a wave packet of atoms. However, the freedom of the inverse engineering approa…
Reverse engineering protocols for controlling spin dynamics
Qi Zhang, Xi Chen, D. Guery-Odelin
We put forward reverse engineering protocols to shape in time the components of the magnetic field to manipulate a single spin, two independent spins with different gyromagnetic fa…
Optimal shortcuts for atomic transport in anharmonic traps
Qi Zhang, J. G. Muga, D. Guéry-Odelin +1
We design optimal trajectories to transport cold atoms in anharmonic traps, combining invariant-based inverse engineering, perturbation theory, and optimal control theory. The anha…
Fast and optimal transport of atoms with non-harmonic traps
Qi Zhang, Xi Chen, David Guéry-Odelin
We investigate the fast transport of an atom or a packet of atoms by different kinds of non-harmonic traps including power-law traps. The study is based on the reverse engineering…
