Entanglement detection in high dimensional systems is a NP-hard problem since it is lacking
an efficient way. Given a bipartite quantum state of interest free entanglement can be …

We demonstrate the detection of bipartite bound entanglement as predicted by the
Horodecki's in 1998. Bound entangled states, being heavily mixed entangled quantum …

From a practical perspective it is advantageous to develop methods that verify entanglement
in quantum states with as few measurements as possible. In this paper we investigate the …

Entanglement has recently been recognized as an energy resource which can outperform
classical resources if decoherence is relatively low. Multi-atom entangled states can mutate …

Preparing and certifying bound entangled states in the laboratory is an intrinsically hard
task, due to both the fact that they typically form narrow regions in state space, and that a …

In the present paper, we investigate the efficacy of Dzyaloshinskii–Moriya (DM) interaction to
convert the bound entangled states into free entangled states. We consider the tripartite …

Recent studies on quantum Fisher information (QFI) have been focused mostly on qubit
systems within the context of how entanglement helps surpassing the classical limit of …

In this work, we experimentally created and characterized a class of qubit-ququart PPT
(positive under partial transpose) entangled states using three nuclear spins on an nuclear …

We propose a scheme for distillation of free bipartite entanglement from bipartite bound
entangled states. The crucial element of our scheme is an ancillary system that is coupled to …

The bound entangled state carries noisy entanglement and it is very hard to distill but the
usefulness of bound entangled states has been depicted in different applications. This …
