It has been recently pointed out [V. Giovannetti, S. Lloyd, and L. Maccone, Europhys. Lett. 62, 615 (2003)] that, for certain classes of states, quantum entanglement enhances the …
The concept of quantum speed limit-time (QSL) was initially introduced as a lower bound to the time interval that a given initial state ψ I may need so as to evolve into a state orthogonal …

We prove that rank-three bipartite entangled states are distillable. So there are no bound rank-three bipartite entangled states. By using this fact, we present some families of rank …

The quantum relative Rényi entropy of two noncommuting density matrices was recently defined from which its conditional entropy is deduced. This framework is here extended to …
The maximally entangled mixed states of Munro [Phys. Rev. A 64, 030302 (2001)] are shown to exhibit interesting features vis á vis conditional entropic measures. The same …

In any bipartition of a quantum state, it is proved that the negative values of the conditional version of sandwiched Tsallis relative entropy necessarily imply quantum entanglement. For …

Entanglement criteria for general (pure or mixed) states of systems consisting of two identical fermions are introduced. These criteria are based on appropriate inequalities …
The separability in multiqubit pure and mixed GHZ and W states with an accelerating qubit has been characterized using Abe Rajagopal (AR) $ q $-conditional entropy. We observe …

The thermal entanglement of the Hubbard dimer (two-site Hubbard model) has been studied with the nonextensive statistics. We have calculated the auto-correlation (Oq), pair …
