    "abstract": "Strong subadditivity inequality for a three-particle composite system is an\nimportant inequality in quantum information theory which can be studied via a\nfour-particle entangled state. We use two three-level atoms in $\\Lambda$\nconfiguration interacting with a two-mode cavity and the Raman adiabatic\npassage technique for the production of the four-particle entangled state.\nUsing this four-particle entanglement, we study for the first time various\naspects of the strong subadditivity inequality.",
