We prove exactly that the squared entanglement of formation, which quantifies the bipartite
entanglement, obeys a general monogamy inequality in an arbitrary multiqubit mixed state …

We explore the quantum correlation distribution in multipartite quantum states based on the
square of quantum discord (SQD). For tripartite quantum systems, we derive the necessary …

We show exactly that the squared entanglement of formation (SEF) obeys a set of
hierarchical monogamy relations for an arbitrary N-qubit mixed state. Based on this set of …

We consider the problem of separability of quantum channels via the Choi matrix
representation given by the Choi-Jamiołkowski isomorphism. We explore three classes of …

We analyze the multipartite entanglement evolution of three-qubit mixed states composed of
a GHZ state and a W state. For a composite system consisting of three cavities interacting …

This paper contains two main contents. In the first part, we provide two counterexamples of
monogamy inequalities for the squared entanglement negativity: one three-qutrit pure state …

The maximally entangled state can be in a mixed state as well as the well-known pure state.
Taking the negativity as a measure of entanglement, we study the entanglement dynamics of …

We investigate the multipartite entanglement dynamics of a many-body system consisting of
N identical two-level atoms locally embedded in their own band-gap photonic crystals. It is …

We explore two different geometric quantum discords defined respectively via the trace norm
(GQD-1) and Hilbert-Schmidt norm (GQD-2) in multipartite systems. A rigorous hierarchy …
