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…
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…
Local available quantum correlations of X states: The symmetric and anti-symmetric cases
Hermann Albrecht, David Bellorin, Douglas F. Mundarain
Local available quantum correlations (LAQC), as defined by Mundarain et al., are analyzed for 2-qubit X states with local Bloch vectors of equal magnitude. Symmetric X-states are i…
Comment on `Local available quantum correlations for Bell Diagonal states and markovian decoherence'
David M. Bellorin R., Hermann L. Albrecht Q
In this brief paper, we complete the analysis presented previously in [RMF 64 (2018) 662-670, arXiv:1803.02426] regarding the quantifiers of the classical correlations and the so-c…
Maximal singlet fraction vs. maximal achievable fidelity as proper entanglement measures
Hermann L. Albrecht Q., Douglas F. Mundarain
We review some parametric families of 2-qubit states for which concurrence and maximal singlet fraction (MSF) have different and even opposite behaviour. For states considered in t…
