The collective effects of Markovian and non‐Markovian classical fields on the dynamics of entanglement, coherence, and quantum state mixing in a three‐qubit mixed entangled state …
A quantum internet aims at harnessing networked quantum technologies, namely by distributing bipartite entanglement between distant nodes. However, multipartite …
We study under what circumstances a separable bipartite system AB can or cannot become entangled through local interactions with a bilocal entangled source S 1-S 2. We obtain …
In traditional quantum metrology protocols, the initial multipartite entangled pure quantum probes are considered to be isolated, ie, free of quantum many-body effects. Here, we study …
We review and generalize the recently introduced framework of entropy vectors for detecting and quantifying genuine multipartite entanglement in high-dimensional multicomponent …
We investigate linear maps between matrix algebras that remain positive under tensor powers, ie, under tensoring with n copies of themselves. Completely positive and completely …

The genuine multiparticle negativity is a measure of genuine multiparticle entanglement which can be numerically calculated. We present several results of how this entanglement …
We analyze general laws of continuous-variable entanglement dynamics during the deterministic attenuation and amplification of the physical signal carrying the entanglement …

We investigate the robustness of genuine multiparticle entanglement under decoherence. We consider different kinds of entangled three-and four-qubit states as well as random pure …
