Permutation asymmetry inducing entanglement between degrees of freedom in multiphoton states
F. W. Sun, B. H. Liu, C. W. Wong +1
We describe and examine entanglement between different degrees of freedom in multiphoton states based on the permutation properties. From the state description, the entanglement co…
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…
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…
Entanglement and interference between different degrees of freedom of photons states
F. W. Sun, B. H. Liu, Y. F. Huang +3
In this paper, photonic entanglement and interference are described and analyzed with the language of quantum information process. Correspondingly, a photon state involving several…
Stimulated emission of two photons in parametric amplification and its interpretation as multi-photon interference
F. W. Sun, B. H. Liu, Y. X. Gong +3
Stimulated emission of two photons is observed experimentally in the parametric amplification process and is compared to a three-photon interference scheme. We find that the underl…
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…
