Entanglement is an important resource for quantum technologies. There are many ways
quantum systems can be entangled, ranging from the two-qubit case to entanglement in …

We present an overview of the quantitative theory of single-copy entanglement in finite-
dimensional quantum systems. In particular we emphasize the point of view that different …

We generate and characterize entangled states of a register of 20 individually controlled
qubits, where each qubit is encoded into the electronic state of a trapped atomic ion …

Small self-contained quantum thermal machines function without external source of work or
control but using only incoherent interactions with thermal baths. Here we investigate the …

We explore the structure of multipartite quantum systems which are entangled in multiple
degrees of freedom. We find necessary and sufficient conditions for the characterization of …

We find an algebraic formula for the N-partite concurrence of N qubits in an X matrix. X
matrices are density matrices whose only nonzero elements are diagonal or antidiagonal …

A small quantum absorption refrigerator, consisting of three qubits, is discussed in the
transient regime. We discuss time scales for coherent dynamics, dam**, and approach to …

We investigate the fundamental limitations imposed by thermodynamics for creating
correlations. Considering a collection of initially uncorrelated thermal quantum systems, we …

The excitations of nucleon resonances with hidden charm, N cc¯*, in γ p reactions are
investigated by using the predictions from the available meson-baryon (MB) coupled …

We derive a general framework that lifts any set of bipartite to multipartite entanglement
witnesses and we show how positive maps can naturally be incorporated into this …
