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…
