Local available quantum correlations of non-symmetric X states
David Bellorin, Hermann Albrecht, Douglas F. Mundarain
Local available quantum correlations (LAQC), as defined by Mundarain et al., are analyzed for non-symmetric 2-qubit X states, that is, X-states that are not invariant under the exc…
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…
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…
Local available quantum correlations for Bell Diagonal states and markovian decoherence
Hermann Albrecht, Douglas Mundarain, Mario Caicedo
Local available quantum correlations (LAQCs), as defined by Mundarain et al. [19], are analytically determined for Bell Diagonal states. Using the Kraus operators formalism [10], w…
The power of a control qubit in weak measurements
Raul Coto, Víctor Montenegro, Vitalie Eremeev +2
In the late 80s, a curious effect suggested by Aharanov, Albert and Vaidman opened up new vistas regarding quantum measurements on weakly coupled systems. There, a combination of a…
Entanglement sudden-death time: a geometric quantity
Ramsés Sánchez, Esteban Isasi, Douglas Mundarain
We study the entanglement evolution of the set of Bell diagonal states for a two-qubit system coupled to two independent vacuum noise sources. This set can be represented geometric…
