Quantum Correlations in Werner Derivatives

Quantum Correlations in Werner Derivatives

Quantum correlations in Werner derivatives are studied with two different approaches, i.e., measurement-induced disturbance (MID) [Phys. Rev. A77(2008) 022301] and ameliorated MID (AMID) [J. Phys. A 44 (2011) 352002], They are derived via strict deductions with MID while numerically calculated via t...

Zusammenfassung:Quantum correlations in Werner derivatives are studied with two different approaches, i.e., measurement-induced disturbance (MID) [Phys. Rev. A77(2008) 022301] and ameliorated MID (AMID) [J. Phys. A 44 (2011) 352002], They are derived via strict deductions with MID while numerically calculated via the measurement optimization with AMID. Interestingly, quantum correlations captured with both approaches are completely coincident. Moreover, some distinct features of the quantum correlations and their underlying physics are exposed via analyses and discussions.
