Four-Photon Interference with Asymmetric Beam Splitters

B. H. Liu, F. W. Sun, Y. X. Gong +3

Two experiments of four-photon interference are performed with two pairs of photons from parametric down-conversion with the help of asymmetric beam splitters. The first experiment…

Physical accessible transformations on a finite number of quantum states

Xiang-Fa Zhou, Qing Lin, Yong-Sheng Zhang +1

We consider to treat the usual probabilistic cloning, state separation, unambiguous state discrimination, \emph{etc} in a uniform framework. All these transformations can be regard…

One-step preparation of cluster states in quantum dot molecules

Guo-Ping Guo, Hui Zhang, Tao Tu +1

Cluster states, a special type of highly entangled states, are a universal resource for measurement-based quantum computation. Here, we propose an efficient one-step generation sch…

Compatibility conditions from multipartite entanglement measures

Jian-Ming Cai, Zheng-Wei Zhou, Shun Zhang +1

We consider an arbitrary d_{1}\otimes d_{2}\otimes ... \otimes d_{N} composite quantum system and find necessary conditions for general m-party subsystem states to be the reduced s…

Experimental entanglement verification and quantification via uncertainty relations

Zhi-Wei Wang, Yun-Feng Huang, Xi-Feng Ren +2

We report on experimental studies on entanglement quantification and verification based on uncertainty relations for systems consisting of two qubits. The new proposed measure is s…

Unambiguous discrimination of mixed states: A description based on system-ancilla coupling

Xiang-Fa Zhou, Yong-Sheng Zhang, Guang-Can Guo

We propose a general description on the unambiguous discrimination of mixed states according to the system-environment coupling, and present a procedure to reduce this to a standar…
