Experimental Measurement of Lower and Upper Bounds of Concurrence for Mixed Quantum States
Xiao-Ling Niu, Yan-Xiao Gong, Jian Li +5
We experimentally measure the lower and upper bounds of concurrence for a set of two-qubit mixed quantum states using photonic systems. The measured concurrence bounds are in agree…
Dependence of the decoherence of polarization states in phase-damping channels on the frequency spectrum envelope of photons
Yan-Xiao Gong, Yong-Sheng Zhang, Yu-Li Dong +3
We consider the decoherence of photons suffering in phase-damping channels. By exploring the evolutions of single-photon polarization states and two-photon polarization-entangled s…
Methods for linear optical quantum Fredkin gate
Yan-Xiao Gong, Guang-Can Guo, Timothy C. Ralph
We consider the realization of quantum Fredkin gate with only linear optics and single photons. First we construct a heralded Fredkin gate using four heralded controlled-not (CNOT)…
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…
