- Enhancing parameter estimation precision by non-Hermitian operator process
- QUANTUM INFORMATION PROCESSINGGuo, You-neng Fang, Mao-fa Wang, Guo-you Hang, Jiang Zeng, Ke 出版年：2017
- Recently, Zhong et al. (Phys Rev A 87: 022337, 2013) investigated the dynamics of quantum Fisher information (QFI) in the presence of decoherence. We here reform their results and propose two schemes to enhance and prese...
- Enhancing parameter precision of optimal quantum estimation by quantum screening
- CHINESE PHYSICS BHuang, Jiang Guo, You-Neng Xie, Qin 出版年：2016
- We propose a scheme of quantum screening to enhance the parameter-estimation precision in open quantum systems by means of the dynamics of quantum Fisher information. The principle of quantum screening is based on an aux...

- Davies theory for teleportation of quantum Fisher information under decoherence
- LASER PHYSICS LETTERSGuo, You-Neng Peng, Hu-Ping Yang, Cheng Xie, Qin Zeng, Ke 出版年：2019
- We have investigated the teleportation of quantum Fisher information (QFI) for a single-qubit system by using two different maximally entangled pure states as resources influenced by a Davies-type Markovian environment. ...
- Dominance of plasma-induced modulation in terahertz generation from gas filament
- OPTICS EXPRESSGuo, Huicheng Du, Henglei Zhan, Qiang Zhang, Xiaoxue Wang, Wenkang Liu, Chengpu 出版年：2024
- In this paper, we revisit the fundamental mechanism responsible for terahertz generation from laser-induced plasma filament based on the photocurrent model by employing a blend of analytical calculation and numerical sim...
- Non-Markovianity for a qubit system driven by a classical phase noisy laser
- EUROPEAN PHYSICAL JOURNAL DGuo, Youneng Fang, Maofa Zhang, Shiyang Huang, Jiang Liu, Xiang 出版年：2014
- In this paper, the degree of non-Markovian behaviour for a qubit system driven by a classical phase noisy laser (CPNL) is investigated. We analyse the dynamics of the rate of change of the trace distance in two different...
- Enhancing the Precision of Parameter Estimation in Band Gap
- INTERNATIONAL JOURNAL OF THEORETICAL PHYSICSHuang, J. Zhan, Q. Liu, Z. K. 出版年：2016
- Recently, the dynamics of quantum Fisher information(QFI) in various environment are investigated and many kinds of schemes to overcome the drawback of decoherence are designed. Here we propose the pseudomode method to e...
- Dynamical Change of Quantum Fisher Information of Cavity-Reservoir Systems
- COMMUNICATIONS IN THEORETICAL PHYSICSHuang, Jiang Xie, Qin 出版年：2016
- We study the quantum Fisher information (QFI) dynamics of the phase parameter in the enlarged cavity reservoir systems at zero temperature under two situations of large N limit and non-Markovian environment, respectively...

- Protecting Qubit-Qubit Entanglement by Quantum Screening
- INTERNATIONAL JOURNAL OF THEORETICAL PHYSICSShi, W. Q. Huang, J. 出版年：2017
- We study the entanglement protection between two identical qubits interacting with independent zero-temperature reservoir beyond the Born-Markoivan approximation. The principle is based on an analog of a zero-ground quan...
