Efficient construction of 2-D cluster states with probabilistic quantum gates
Qing Chen, Jianhua Cheng, Ke-Lin Wang +1
We propose an efficient scheme for constructing arbitrary 2-D cluster states using probabilistic entangling quantum gates.In our scheme, the 2-D cluster state is constructed with s…

Comparison of variational and CSE methods to polaron ground-state energy
Qing Chen, Ke-Lin Wang, Yi Wang
Taking the same trial wave function, the ground-state energy of Fröhlich polaron is investigated by variational method and coherent-state expansion (CSE) one, respectively. Within…

General Multimode Squeezed States
Gan Qin, Ke-lin Wang, Tong-zhong Li
By the complex multimode Bogoliubov transformation, we obtain the general forms of squeeze operators and squeezed states including squeezed vacuum states, squeezed coherent states,…
