Characterization of the measurement uncertainty dynamics in an open system
Xi-Hao Fang, Fei Ming, Dong Wang
Uncertainty principle plays a crucial role in quantum mechanics, because it captures the essence of the inevitable randomness associated with the outcomes of two incompatible quant…
Necessary and sufficient criterion of steering for two-qubit T states
Xiao-Gang Fan, Huan Yang, Fei Ming +3
Einstein-Podolsky-Rosen (EPR) steering is the ability that an observer persuades a distant observer to share entanglement by making local measurements. Determining a quantum state…
Inequality relation between entanglement and Bell nonlocality for arbitrary two-qubit states
Xiao-Gang Fan, Zhi-Yong Ding, Fei Ming +3
Entanglement and Bell nonlocality are used to describe quantum inseparabilities. Bell-nonlocal states form a strict subset of entangled states. A natural question arises concerning…
The intrinsic relations of quantum resources in multiparticle systems
Wen-Yang Sun, Dong Wang, Bao-Long Fang +4
Quantum resources play crucial roles for displaying superiority in many quantum communication and computation tasks. To reveal the intrinsic relations hidden in these quantum resou…
Effects of Hawking radiation on the entropic uncertainty in a Schwarzschild space-time
Dong Wang, Wei-Nan Shi, Ross D. Hoehn +4
Heisenberg uncertainty principle describes a basic restriction on observer's ability of precisely predicting the measurement for a pair of non-commuting observables, and virtually…
