• Abstract: The quantum entropy cones (QEC) for $W_N$ states of qubits and $W_N^d$ states of qudits are computed. These cones emerge as symmetrized quantum entropy cones (SQEC) for arbitrary $N$ and $d$. Directed graph models are presented which describe the SQEC for $W_N$ states and $W_N^d$ states. Monogamous mutual information (MMI) is violated for all $N>3$.

  We prove monogamy of entanglement bounds by certifying the ground state energy of the Maximal Entanglement problem. We show that a simple matching-based algorithm outputs a state with energy at least $1/d$ of the ground state energy for general graphs.

  We show how to reduce the geometry of degenerate states to the non-abelian connection $A$. We find independent invariants associated with each triple of subspaces. Some of them generalize the Berry-Pancharatnam phase, and some do not have analogues for 1-dimensional subspaces.

  We show that, contrary to the claim by Kumar [Phys. Rev. A 96, 012332], the quantum dual total correlation of an $n$-partite quantum state cannot be represented. We argue that the latter fails to yield a finite value for generalized $n$-partite Greenberger-Horne-Zeilinger states.

• Tip of the Quantum Entropy Cone [1.1606619391009658]
  Relations among von Neumann entropies of different parts of an $N$-partite quantum system have direct impact on our understanding of diverse situations. We show that while it is always possible to up-scale an entropy vector to arbitrary integer multiples it is not always possible to down-scale it to arbitrarily small size.

  A pure state of $N$ parties with local dimension $d$ is called a $k$-uniform state if all the reductions to $k$ parties are maximally mixed. We show that when $dgeq 4k-2$ is a prime power, there exists a $k$-uniform state for any $Ngeq 2k$ (resp. $2kleq Nleq d+1$)

• Bosonic quantum communication across arbitrarily high loss channels [68.58838842613457]
  A general attenuator $Phi_lambda, sigma$ is a bosonic quantum channel that acts by combining the input with a fixed environment state. We show that for any arbitrary value of $lambda>0$ there exists a suitable single-mode state $sigma(lambda)$. Our result holds even when we fix an energy constraint at the input of the channel, and implies that quantum communication at a constant rate is possible even in the limit of arbitrarily low transmissivity.
