Multi-observable Uncertainty Equality based on the sum of standard deviations in the qubit system
Xiao Zheng, Shaoqiang Ma, Guofeng Zhang
We construct a multi-observable uncertainty equality as well as an inequality based on the sum of standard deviations in the qubit system. The obtained equality indicates that the…
Phase Anti-Synchronization dynamics between Mechanical Oscillator and Atomic Ensemble within a Fabry-Perot Cavity
Shao-Qiang Ma, Xiao Zheng, Guo-Feng Zhang
Phase synchronization refers to a kind of collective phenomenon that the phase difference between two or more systems is locked, and it has widely been investigated between systems…
Criterion of Quantum Phase Synchronization in Continuous Variable Systems by Local Measurement
Shao-Qiang Ma, Xiao Zheng, Guo-Feng Zhang
Phase synchronization was proved to be unbounded in quantum level, but the witness of phase synchronization is always expensive in terms of the quantum resource and non-local measu…
Detecting Non-Markovianity via Linear Entropy of Choi State
Xiao Zheng, Shao-Qiang Ma, Guo-Feng Zhang
Non-Markovian dynamics detection is one of the most popular subjects in the quantum information science. In this paper, a linear-entropy-based non-Markovianity witness scheme is co…
Multiparticle Entanglement Resolution Analyzer based on Quantum-Control-Assisted Uncertainty Relation
Shao-Qiang Ma, Xiao Zheng, Guo-Feng Zhang +3
We construct a quantum-control-assisted multi-observable variance-based uncertainty relation, and the uncertainty relation obtained indicates that we can prepare a quantum state, i…
A Unified and Strengthened Framework for the Uncertainty Relation
Xiao Zheng, Shao-Qiang Ma, Guo-Feng Zhang +2
We provide a unified and strengthened framework for the product form and the sum form variance-based uncertainty relations by constructing a unified uncertainty relation. In the un…
The effects of different quantum feedback operator types on the parameter precision of detection efficiency in optimal quantum estimation
Shao-Qiang Ma, Han-Jie Zhu, Guofeng Zhang
The effects of different quantum feedback types on the estimation precision of the detection efficiency are studied. It is found that the precision can be more effective enhanced b…
The transport character of quantum state in one-dimensional coupled-cavity-arrays: effect of the number of photons and entanglement degree
Shao-Qiang Ma, Guo-Feng Zhang
The transport properties of the photons injected into one-dimensional coupled-cavity-arrays (CCAs) are studied. It is found that the number of photons cannot change the evolution c…
