A Quantum Communication Protocol Transferring Unknown Photons Using Path-Polarization Hybrid Entanglement
《Chinese Physics Letters》2013年第4期5-9,共5页Jino Heo Chang Ho Hong Jong In Lim Hyung Jin Yang 
the MKE(The Ministry of Know ledge Economy),Korea under the ITRC(Information Technology Research Center)support program(NIPA-2012-H0301-12-3007)supervised by the NIPA(National IT Industry Prormotion A gency).
We propose a protocol for transferring photons of unknown states to a distant location using path-polarization hybrid entanglement.Our protocol uses a polarizing beam splitter(PBS),a beam splitter(BS),a CNOT-operation...

Teleporting an Unknown Two-qubit Entangled State via Ion-Trap Systems
《Chinese Physics Letters》2009年第1期130-131,共2页艾凌艳 杜刚 朱诗亮 张智明 
Supported by the National Natural Science Foundation of China under Grant No 60578055, and the National Basic Research Programme of China under Grant No 2007CB925204.
We propose a scheme for teleportation of an unknown two-qubit entangled state via trapped ions. In this scheme, we use the GHZ state as a quantum channel and the success probability can reach 1. The distinct advantage...

Concentration of Unknown Atomic Entangled States via Entanglement Swapping through Raman Interaction
《Chinese Physics Letters》2008年第9期3142-3145,共4页邹金华 胡响明 
Supported by National Natural Science Foundation of China under Grant Nos 10574052 and 60778005.
We show that entanglement concentration of unknown atomic entangled states is achieved via the implementation of entanglement swapping based on Raman interaction in cavity QED. A maximally entangled state is obtained ...

Information-Disturbance Tradeoff in Estimating the Unknown Three-Qubit GHZ State
《Chinese Physics Letters》2007年第6期1456-1459,共4页张胜利 邹旭波 李科 金晨辉 郭光灿 
Supported by the National Basic Research Programme of China, the National Natural Science Foundation of China under Grant Nos 10674128 and 60121503, the Knowledge Innovation Project and the Hundreds of Talents Programme of Chinese Academy of Sciences, and the Doctoral Foundation of the Education Ministry of China under Grant No 20060358043.
In a recent paper, Sacchi （Phys. Rev. Lett. 96 （2006） 220502） studied the information-disturbance tradeoff in estimating an unknown two-qubit maximally entangled state. In this study, we explore the tradeoff in es...

Scheme for Concentration of Unknown Greeberger-Horne-Zeilinger Entangled States via Cavity Decay
《Chinese Physics Letters》2007年第3期602-605,共4页张小伟 刘翔 唐筱芳 唐有良 
Supported by the National Natural Science Foundation of China under Grant No 10374025, and the Scientific Research Fund of Hunan Provincial Education Department under Grant No 05c415.
We present a scheme for entanglement concentration of an unknown atomic non-maximally entangled GHZ state via cavity decay. In the scheme, the atom trapped in a cavity is manipulated by laser field, so the maximally e...

Teleportation of an Unknown Quantum State via Partly Entangled States被引量：2
《Chinese Physics Letters》2000年第10期703-704,共2页FENG Xun-Li Gong Shang-Qing WANG ZHONG-YANG XU Zhi-Zhan 
Supported by the China Postdoctoral Science Foundation,and the Natural Science Foundation of Shanghai(Grant No.99ZA14052).
The teleportation of an unknown quantum state from one observer to another is of great importance in quantum information. In the standard teleportation scheme, a maximally entangled state is demanded. However, it is i...
