Proposal for optical parity state re-encoder
Y. X. Gong, A. J. F. Hayes, G. C. Guo +1
We propose a re-encoder to generate a refreshed parity encoded state from an existing parity encoded state. This is the simplest case of the scheme by Gilchrist et al. (Phys. Rev.…
Entanglement detection beyond the cross-norm or realignment criterion
Cheng-Jie Zhang, Yong-Sheng Zhang, Shun Zhang +1
Separability problem, to decide whether a given state is entangled or not, is a fundamental problem in quantum information theory. We propose a powerful and computationally simple…
Field Experimental "Star Type" Metropolitan Quantum Key Distribution Network
Wei Chen, Zheng-F Han, Tao Zhang +10
Quantum key distribution (QKD) network has recently attracted growing attentions. Due to the special characteristics of quantum information, to build a full-connectivity QKD networ…
Demonstration of Temporal Distinguishability of Three and Four Photons with Asymmetric Beam Splitter
Z. Y. Ou, B. H. Liu, F. W. Sun +3
By using an asymmetric beam splitter, we observe the generalized Hong-Ou-Mandel effects for three and four photons, respectively. Furthermore, we can use this generalized Hong-Ou-M…
Analogue to multiple electromagnetically induced transparency in all-optical drop-filter systems
Yun-Feng Xiao, Xu-Bo Zou, Wei Jiang +2
We theoretically study a parallel optical configuration which includes N periodically coupled whispering-gallery-mode resonators. The model shows an obvious effect which has a dire…
Experimental Measurement of Multi-dimensional Entanglement via Equivalent Symmetric Projection
F. W. Sun, J. M. Cai, J. S. Xu +5
We construct a linear optics measurement process to determine the entanglement measure, named \emph{I-concurrence}, of a set of dimensional two-photon entangled pure s…
