Local-available quantum correlation swapping in one-parameter X states
Hermann L. Albrecht
Although introduced for entanglement, quantum repeaters and swapping protocols have been analyzed for other quantum correlations (QC), such as quantum discord. In 2015, Mundarain a…

On the issues arising when defining an X gate for qudits: Extending the Bit-Flip channel to -dimensional systems
Jean F. Gomez, Hermann L. Albrecht
Given the current interest in quantum information tasks involving higher-dimensional systems, we discuss some of the issues that appear when extending the bit-flip channel to qutri…

Quantum correlations in mutually unbiased bases and non-Markovian dephasing
Hermann L. Albrecht, David M. Bellorin
Wu et al. introduced a symmetric measure in terms of mutually unbiased bases (MUBs) that quantifies residual quantum correlations (RQC). The definition of this measure invo…
