Sudden Change of Quantum Discord under Single Qubit Noise
Li-Xing Jia, Bo Li, R. -H. Yue +1
We show that the sudden change of quantum correlation can occur even when only one part of the composite entangled state is exposed to a noisy environment. Our results are illustra…
Genuine Correlations of Tripartite System
Liming Zhao, Xueyuan Hu, R. -H. Yue +1
We define genuine total, classical and quantum correlations in tripartite systems. The measure we propose is based on the idea that genuine tripartite correlation exists if and onl…
Testing quantum entanglement with local measurement
Qing Xie, X. -X. Wu, X. -M. Ding +3
We propose to detect quantum entanglement by a condition of local measurments. We find that this condition can detect efficiently the pure entangled states for both discrete and co…
An Ideal Channel of Long Distance Entanglement in Spin Systems
Xiao-Qiang Xi, T. Zhang, R. H. Yue +2
We propose a scheme for using spin chain to realize an ideal channel of long distance entanglement. The results show that there has different entanglement in different Hilbert subs…
Designing a Spin Channel for Perfect Quantum Communication
Xiao-Qiang Xi, T. Zhang, R. H. Yue +2
We propose a scheme for using a spin chain with fixed symmetry interaction as a channel for perfect quantum communication. The perfect quantum communication is determined by the ei…
Pairwise Entanglement and Local Polarization of Heisenberg Model
Xiao-Qiang Xi, R. H. Yue, W. M. Liu
The pairwise entanglement and local polarization of the ground state are discussed by studying the Heisenberg XX model in finite qubit case. The results show that: the ground state…
