arXiv:2204.04532

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 $N > 3$ .
