Tetrapartite entanglement measures of W-Class in noninertial frames
Ariadna J. Torres-Arenas, Edgar O. Lopez-Zuniga, J. Antonio Saldana-Herrera +3
We present the entanglement measures of a tetrapartite W-Class entangled system in noninertial frame, where the transformation between Minkowski and Rindler coordinates is applied.…
Geometric quantum discord of a Jaynes-Cummings atom and an isolated atom
Wen-Chao Qiang, Lei Zhang, Hua-Ping Zhang
We studied the geometric quantum discord of a quantum system consisted of a Jaynes- Cummings atom, a cavity and an isolated atom. The analytical expressions of the geometric quantu…
Geometric global quantum discord of two-qubit X states
Wen-Chao Qiang, Hua-Ping Zhanga, Lei Zhang
Xu [Jianwei Xu, J. Phys. A: Math. Theor. 45 405304 (2012)] generalized geometric quantum discord [B.Dakic, V. Vedral, and C . Brukner, Phys. Rev. Lett. 105 190502 (2010)] to multip…
Entanglement of formation for qubit-qudit system using partition of qudit sytem into a set of qubit system
Wen-Chao Qiang, W. B. Cardoso
Gerjuoy [Phys. Rev. A 67, 052308 (2003)] has derived a closed- form lower bound for the entanglement of formation of a mixed qubit-qudit system (qudit system has d levels with d>=3…
Effects of impurity on fidelity of quantum state transfer via spin channels
Wen-Wen Zhang, Ming-Liang Hu, Dong-Ping Tian
By adopting the concept of fidelity, we investigated efficiency of quantum state transfer with the XX chain as the quantum channel. Different from the previous works, we concentrat…
NMR Experimental Demonstration of Probabilistic Quantum Cloning
Hongwei Chen, Dawei Lu, Bo Chong +4
The method of quantum cloning is divided into two main categories: approximate and probabilistic quantum cloning. The former method is used to approximate an unknown quantum state…
