Dynamical speedup of a two-level system induced by coupling in the hierarchical environment
Kai Xu, Guo-Feng Zhang, Wu-Ming Liu
We investigate the dynamics of a two-level system in the presence of an overall environment composed of two layers. The first layer is just one single-mode cavity which decays to m…

Experimental Realization of Nonadiabatic Shortcut to Non-Abelian Geometric Gates
Tongxing Yan, Bao-Jie Liu, Kai Xu +10
When a quantum system is driven adiabatically through a parametric cycle in a degenerate Hilbert space, the state would acquire a non-Abelian geometric phase, which is stable and f…

Hierarchical environment-assisted dynamical speedup control
Kai Xu, Wei Han, Ying-Jie Zhang +2
We investigate the qubit in the hierarchical environment where the first level is just one lossy cavity while the second level is the N-coupled lossy cavities. In the weak coupling…
