Speeding up adiabatic state conversion in optomechanical system
Feng-Yang Zhang, Wen-Lin Li, Yan Xia
Speeding up adiabatic method has attracted much attention with the wide applications in quantum information processing. In this paper, two kinds of methods, Lewis-Riesenfeld invari…
Flexible and experimentally feasible shortcut to quantum Zeno dynamic passage
Wenlin Li, Chong Li, Heshan Song
We propose and discuss a theoretical scheme to speed up Zeno dynamic passage by an external acceleration Hamiltonian. This scheme is a flexible and experimentally feasible accelera…
Strong coupling between two spin ensembles via a large Josephson junction
Feng-Yang Zhang, Wenlin Li, Chui-Ping Yang
We propose a method to achieve strong coupling between a spin ensemble and a large Josephson junctions (LJJ). Then, the strong coupling between two spin ensembles can be induced by…
