The recognition of the key role entanglement plays in the understanding of the radical departure of quantum from classical physics came historically remarkably late. In the early …
In order to witness multipartite correlations beyond pairwise entanglement, spin-squeezing parameters are analytically calculated for a spin ensemble in a collective initial state under …
I explore entanglement dynamics in a three qubit system comparing the ability of entanglement witnesses to detect tripartite entanglement to the phenomenon of …
We investigate the decay of entanglement, due to decoherence, of multiqubit systems that are initially prepared in highly (in some cases maximally) entangled states. We assume that …
We study the dynamics of the entanglement structure of a multipartite system experiencing a dissipative evolution. We characterize the processes leading to a particular form of output …
The opportunity to build quantum technologies operating with elementary quantum systems with more than two levels is now increasingly being examined, not least because of the …

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 …
I explore the entanglement dynamics of a three-qubit system in an initial X state undergoing decoherence including the possible exhibition of entanglement sudden death. To quantify …
We study dynamics of genuine entanglement for quantum states of three and four qubits under non-Markovian dephasing. Using a computable entanglement monotone for …
