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…

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…
