Deterministic entanglement purification and complete nonlocal Bell-state analysis with hyperentanglement
Yu-Bo Sheng, Fu-Guo Deng
Entanglement purification is a very important element for long-distance quantum communication. Different from all the existing entanglement purification protocols (EPPs) in which t…
Efficient faithful qubit transmission with frequency degree of freedom
Xi-Han Li, Bao-Kui Zhao, Yu-Bo Sheng +2
We propose an efficient faithful polarization-state transmission scheme by utilizing frequency degree of freedom besides polarization and an additional qubit prepared in a fixed po…
Genuine tripartite entanglement in quantum brachistochrone evolution of a three-qubit system
Bao-Kui Zhao, Fu-Guo Deng, Feng-Shou Zhang +1
We explore the connection between quantum brachistochrone (time-optimal) evolution of a three-qubit system and its residual entanglement called three-tangle. The result shows that…
Single-photon entanglement concentration for long-distance quantum communication
Yu-Bo Sheng, Fu-Guo Deng, Hong-Yu Zhou
We present a single-photon entanglement concentration protocol for long-distance quantum communication with quantum nondemolition detector. It is the first concentration protocol f…
Fault tolerant quantum key distribution based on quantum dense coding with collective noise
Xi-Han Li, Bao-Kui Zhao, Yu-Bo Sheng +2
We present two robust quantum key distribution protocols against two kinds of collective noise, following some ideas in quantum dense coding. Three-qubit entangled states are used…
