Phononic entanglement concentration via optomechanical interactions
Shan-Shan Chen, Hao Zhang, Qing Ai +1
Low dissipation, tunable coupling to other quantum systems, and unique features of phonons in the aspects of propagation, detection and others suggest the applications of quantized…
Fast and robust quantum control for multimode interactions by using shortcuts to adiabaticity
Hao Zhang, Xue-Ke Song, Qing Ai +3
Adiabatic quantum control is a very important approach for quantum physics and quantum information processing. It holds the advantage with robustness to experimental imperfections…

Atomic ensembles are effective memory nodes for quantum communication network due to the long coherence time and the collective enhancement effect for the nonlinear interaction bet…
Optimal ancilla-free phase-covariant telecloning of qudits via nonmaximally entangled states
Xin-Wen Wang, Guo-Jian Yang
We study the one-to-two phase-covariant telecloning of a qudit without ancilla. We show that the fidelity of the two clones can reach that of the clones in the optimal ancilla-base…
