Optimal convex approximation of quantum channels based on -affinity
Liqiang Zhang, Chengling Fu, Liuyong Cheng +2
Determining the minimal distance between a target channel and a convex hull of predefined set of implementable channels is a fundamental problem in quantum resource theory, and pro…
Entanglement distribution among distinct mechanical nodes in a quantum network
Zhi-Yuan Fan, Liu-Yong Cheng
We propose two schemes to achieve remote entanglement distribution between two mechanical nodes with a significant frequency mismatch, based on optomechanical systems. The first sc…
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…
Simple implementation of quantum delayed-choice experiment using conventional linear optical elements
Qi Guo, Liu-Yong Cheng, Hong-Fu Wang +1
We propose a simple implementation scheme of quantum delayed-choice experiment in linear optical system without initial entanglement resource. By choosing different detecting devic…
