Efficient multipartite entanglement purification with non-identical states
Hao Qin, Ming-Ming Du, Xi-Yun Li +3
We present an efficient and general multipartite entanglement purification protocol (MEPP) for N-photon systems in Greenberger-Horne-Zeilinger (GHZ) states with non-identical input…

Perfect state transfer and efficient quantum routing: a discrete-time quantum walk approach
Xiang Zhan, Hao Qin, Zhi-hao Bian +2
We show a perfect state transfer of an arbitrary unknown two-qubit state can be achieved via a discrete-time quantum walk with various settings of coin flippings, and extend this m…

A one-dimensional quantum walk with multiple-rotation on the coin
Peng Xue, Rong Zhang, Hao Qin +3
We introduce and analyze a one-dimensional quantum walk with two time-independent rotations on the coin. We study the influence on the property of quantum walk due to the second ro…
