    "abstract": "We introduce a new positive linear map for a single qubit. This map is a\ndecay only in populations of a single-qubit density operator. It is shown that\nan n-fold product of this map may be used for a detection of n-partite\ninseparability of an n-qubit density operator (i.e., detection of impossibility\nof representing a density operator in the form of a convex combination of\nproducts of density operators of individual qubits). This product map is also\ninvestigated in relation to a variant of the entanglement detection method\nmentioned by Laskowski and Zukowski.",
