Quantum correlation and entropic uncertainty in a quantum-dot system
文献摘要：
We explore the dynamical behaviors of the measurement uncertainty and quantum correlation for a vertical quantum-dot system in the presence of magnetic field,including electron-electron interaction and Coulomb-blocked systems.Stem-ming from the quantum-memory-assisted entropic uncertainty relation,the uncertainty of interest is associated with tem-perature and parameters related to the magnetic field.Interestingly,the temperature has two kinds of influences on the variation of measurement uncertainty with respect to the magnetic-field-related parameters.We also discuss the relation between the lower bound of Berta et al.and the quantum discord.It is found that there is a natural competition between the quantum discord and the entropy minΠiBSΠiB(ρA|B).Finally,we bring in two improved bounds to offer a more precise limit to the entropic uncertainty.
