We propose a linear optical protocol to generate three-photon and four-photon entangled states without resorting to entangled sources. The setup in this protoco
The continuous variable quantum key distribution is expected to provide high secret key rate without single photon source and detector, while the lack of the ef
A standard in-beam γ-spectroscopy experiment for 188Pt is performed via the 176Yb(18O,6n) reaction at beam energies of 88 and 95 Me V,and the level scheme for
A bilayer stacked InAs/GaAs quantum dot structure grown by molecular beam epitaxy on an In0.05Ga0.95As metamorphic buffer is investigated.By introducing a InGaA
We discuss a particular d-dimensional Gauss Bonnet-dilatonic universe compactified on S1 motivated from M-theory. We examine the time-evolution of the dynamical
We introduce the concept of truncated states obtained via iterative processes(TSI)and study its statistical features,making an analogy with dynamical systems th
The upgrade project of the Beijing Electron Positron Collider (BEPCII) and its injector linac is working well.The linac upgrade aims at a higher injection rate
