The entropy cones of WNW_N and WNdW_N^d states

preprint2022arXivOpen access

Abstract

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