• Abstract summary: Explicit trade-off inequalities are derived with lower bounds given by the coherence of either bipartite or multipartite reduced density matrices. For pure three-qubit states, it is explicitly shown that the trade-off inequality is lower bounded by the three tangle of quantum entanglement.

• Abstract: We study the trade-off relations given by the l_1-norm coherence of general multipartite states. Explicit trade-off inequalities are derived with lower bounds given by the coherence of either bipartite or multipartite reduced density matrices. In particular, for pure three-qubit states, it is explicitly shown that the trade-off inequality is lower bounded by the three tangle of quantum entanglement.

  We establish the profound equivalence between measures of genuine multipartite entanglement(GME) and their corresponding coherence measures. We find that genuine multipartite steering and nonlocality are present if and only if the coherence exists in the corresponding qubit states.

  Embezzlement of entanglement refers to the task of extracting entanglement from an entanglement resource via local operations and without communication. We show that finite-dimensional approximations of multipartite embezzling states form multipartite embezzling families. We discuss our results in the context of quantum field theory and quantum many-body physics.

  We find tight nonlinear bounds satisfied by all pure states and extend this result by including the three-body correlations. Second, we consider mixed states and conjecture a tight non-linear bound for all three-qubit states. We give criteria to detect different types of multipartite entanglement as well as characterize the rank of the quantum state.

  Given a multipartite quantum system that consists of two-level particles (qubits), one may or may not have access to all the subsystems. Monogamy constraints, reported in this letter, are relations between well known entanglement measures such as one-tangle, two-tangles and three-tangles of an N-qubit pure state.

• Characterizing multipartite entanglement by violation of CHSH inequalities [15.437374103470939]
  Entanglement of high-dimensional and multipartite quantum systems offer promising perspectives in quantum information processing. We consider the overlaps between the maximal quantum mean values and the classical bound of the CHSH inequalities for pairwise-qubit states in two-dimensional subspaces. We show that the concurrence of a pure state in any high-dimensional multipartite system can be equivalently represented by these overlaps.
