Robust population inversion in three-level systems by composite pulses
Cheng Zhang, Yang Liu, Zhi-Cheng Shi +3
In this work, we exploit the idea of composite pulses to achieve robust population inversion in a three-level quantum system. The scheme is based on the modulation of the coupling…
Turnplate of quantum state
Yang Liu, D. L. Zhou
Time-reversal symmetry breaking can enhance or suppress the probability of success for quantum state transfer (QST), and remarkably it can be used to implement the directional QST.…
Transfer arbitrary photon state along a cavity array without initialization
Yang Liu, D. L. Zhou
We propose a quantum state transfer (QST) scheme that transfers any single-mode photon state along a one-dimensional coupled-cavity array (CCA). By building a map from QST in a CCA…
Irreducible many-body correlations in topologically ordered systems
Yang Liu, Bei Zeng, D. L. Zhou
Topologically ordered systems exhibit large-scale correlation in their ground states, which may be characterized by quantities such as topological entanglement entropy. We propose…
Optimized quantum state transfer through an XY spin chain
Yang Liu, D. L. Zhou
Quantum state transfer along a one-dimensional spin chain has become a fundamental ingredient for quantum communication between distant nodes in a quantum network. We study the ave…
Optimal transfer of an unknown state via a bipartite operation
Yang Liu, Yu Guo, D. L. Zhou
A fundamental task in quantum information science is to transfer an unknown state from particle to particle (often in remote space locations) by using a bipartite quantum o…
