High-efficiency alignment-free quantum cryptography based on quantum interference
Qi Guo, Liu-Yong Cheng, Hong-Fu Wang +1
We propose an alternative quantum cryptography protocol using the quantum interference effect. The efficiency of creating sifted key can reach 100\% in principle, which is higher t…
Preparation of entanglement between atoms in spatially separated cavities via fiber loss
Shi-Lei Su, Xiao-Qiang Shao, Qi Guo +3
We propose a scheme to prepare a maximally entangled state for two Lambda-type atoms trapped in separate optical cavities coupled through an optical fiber based on the combined eff…
Enhanced superconductivity in F-doped LaO1-xFxBiSSe
Xiao-Chuan Wang, Dong-Yun Chen, Qi Guo +5
The layered compound LaOBiSSe was successfully synthesized by a two-step solid-state reaction method, which is isostructural with the quaternary compound LaOBiS2 indicated by the p…
Counterfactual quantum-information transfer
Qi Guo, Liu-Yong Cheng, Li Chen +2
We demonstrate quantum information can be transferred between two distant participants without any physical particles travelling between them. The key procedure of the counterfactu…
Nematicons in liquid crystals with negative dielectric anisotropy
Jing Wang, Junzhu Chen, Jinlong Liu +6
We report a theoretical and experimental work on the nematicon in the planar cell containing the nematic liquid crystal with negative dielectric anisotropy, aligned homeotropically…
