Quasi multipartite entanglement measure based on quadratic functions
Jing Zhang, Chun-Wen Li, Re-Bing Wu +2
We develop a new entanglement measure by extending Jaeger's Minkowskian norm entanglement measure. This measure can be applied to a much wider class of multipartite mixed states, a…
A modified quantum adiabatic evolution for the Deutsch-Jozsa problem
Zhaohui Wei, Mingsheng Ying
Deutsch-Jozsa algorithm has been implemented via a quantum adiabatic evolution by S. Das et al. [Phys. Rev. A 65, 062310 (2002)]. This adiabatic algorithm gives rise to a quadratic…
Speedup of quantum state transfer by three- qubit interactions: Implementation by nuclear magnetic resonance
Jingfu Zhang, Xinhua Peng, Dieter Suter
Universal quantum information processing requires single-qubit rotations and two-qubit interactions as minimal resources. A possible step beyond this minimal scheme is the use of t…
Unambiguous discrimination among quantum operations
Guoming Wang, Mingsheng Ying
We address the problem of unambiguous discrimination among a given set of quantum operations. The necessary and sufficient condition for them to be unambiguously distinguishable is…

Gui Lu Long
In this article, we propose a general principle of quantum interference for quantum system, and based on this we propose a new type of computing machine, the duality computer, that…

Chi Zhang, Mingsheng Ying, Bo Qiao
We discuss the problem of designing unambiguous programmable discriminators for any n unknown quantum states in an m-dimensional Hilbert space. The discriminator is a fixed measure…
On Series of Multiqubit Bell's Inequalities
Tomasz Paterek, Wieslaw Laskowski, Marek Zukowski
We overview series of multiqubit Bell's inequalities which apply to correlation functions. We present conditions that quantum states must satisfy to violate such inequalities.
Detection of N-particle entanglement with generalized Bell inequalities
Wieslaw Laskowski, Marek Zukowski
We show that the generalized Bell-type inequality, explicitly involving rotational symmetry of physical laws, is very efficient in distinguishing between true N-particle quantum co…

D. L. Zhou, B. Zeng, J. S. Tang +2
We investigate quantum correlations of the -qubit states via a collective pseudo-spin interaction () on arbitrary pure separable states for a given interval of ti…
Exact Solution for a Two-Level Atom in Radiation Fields and the Freeman Resonances
Dong-Sheng Guo, Yong-Shi Wu, Linn Van Woerkom
Using techniques of complex analysis in an algebraic approach, we solve the wave equation for a two-level atom interacting with a monochromatic light field exactly. A closed-form e…
Modified Bennett-Brassard 1984 Quantum Key Distribution With Two-way Classical Communications
Kai Wen, Gui Lu Long
The quantum key distribution protocol without public announcement of bases is equipped with a two-way classical communication symmetric entanglement purification protocol. This mod…
Density Matrix in Quantum Mechanics and Distinctness of Ensembles Having the Same Compressed Density Matrix
Gui Lu Long, Yi-Fan Zhou, Jia-Qi Jin +2
We clarify different definitions of the density matrix by proposing the use of different names, the full density matrix for a single-closed quantum system, the compressed density m…

Yuan Feng, Runyao Duan, Zhengfeng Ji
The linearity of quantum operations puts many fundamental constraints on the information processing tasks we can achieve on a quantum system whose state is not exactly known, just…
No-relationship between impossibility of faster-than-light quantum communication and distinction of ensembles with the same density matrix
Chuan Wang, Gui Lu Long, Yang Sun
It has been claimed in the literature that impossibility of faster-than-light quantum communication has an origin of indistinguishability of ensembles with the same density matrix.…

Fu-Guo Deng, Gui Lu Long, Hong-Yu Zhou
An efficient quantum secret sharing scheme is proposed. In this scheme, the particles in an entangled pair group form two particle sequences. One sequence is sent to Bob and the ot…
