Effects of Imperfect Gate Operations in Shor's Prime Factorization Algorithm

Hao Guo, Gui-Lu Long, Yang Sun

The effects of imperfect gate operations in implementation of Shor's prime factorization algorithm are investigated. The gate imperfections may be classified into three categories:…

Quantum dynamical theory for squeezing the output of a Bose-Einstein condensate

Hui Jing, Jing-Ling Chen, Mo-Lin Ge

A linear quantum dynamical theory for squeezing the output of the trapped Bose-Einstein condensate is presented with the Bogoliubov approximation. We observe that the non-classical…

Theoretical efficient high capacity Quantum Key Distribution Scheme

Gui Lu Long, Xiao Shu Liu

A theoretical quantum key distribution scheme using EPR pairs is presented. This scheme is efficient in that it uses all EPR pairs in distributing the key except those chosen for c…

Analysis of Density Matrix reconstruction in NMR Quantum Computing

G. L. Long, H. Y. Yan, Yang Sun

Reconstruction of density matrices is important in NMR quantum computing. An analysis is made for a 2-qubit system by using the error matrix method. It is found that the state tomo…

Experimental NMR Realization of A Generalized Quantum Search Algorithm

G. L. Long, H. Y. Yan, Y. S. Li +8

A generalized quantum search algorithm, where phase inversions for the marked state and the prepared state are replaced by phase rotations, is realized in a 2-qubit NMR heter…
