Quantum Fisher Information Flow in Non-Markovian Processes of Open Systems
Xiao-Ming Lu, Xiaoguang Wang, C. P. Sun
We propose to use the quantum Fisher information in characterizing the information flow of open quantum systems. This information-theoretic approach provides a quantitative measure…
Sudden vanishing of spin squeezing under decoherence
Xiaoguang Wang, Adam Miranowicz, Yu-xi Liu +2
In order to witness multipartite correlations beyond pairwise entanglement, spin-squeezing parameters are analytically calculated for a spin ensemble in a collective initial state…
Multi-Stability of Electromagnetically Induced Transparency in Atom-Assisted Optomechanical Cavities
Yue Chang, T. Shi, Yu-xi Liu +2
We study how an oscillating mirror affects the electromagnetically induced transparency (EIT) of an atomic ensemble, which is confined in a gas cell placed inside a micro-cavity wi…
Molecular Ensemble Based Remote Quantum Storage for Charge Qubit via Quasi-Dark State
H. R. Zhang, Y. B. Gao, Z. R. Gong +1
We propose a quantum storage scheme independent of the current time-control schemes, and study a "quantum data bus" (transmission line resonator) in a hybrid system consisting of a…
Quantum switch for single-photon transport in a coupled superconducting transmission line resonator array
Jie-Qiao Liao, Jin-Feng Huang, Yu-xi Liu +2
We propose and study an approach to realize quantum switch for single-photon transport in a coupled superconducting transmission line resonator (TLR) array with one controllable ho…
