    "abstract": "We present here a scheme that relates seemingly two different kinds of\nphysical impossibilities of quantum information processing. We derive, exact\nflipping of three arbitrary states not lying in one great circle is not\npossible with certainty, by using the existence of incomparable states which\nare not interconvertible deterministically by local operations and classical\ncommunications. In contrast, considering the non-existence of exact universal\nflipper, the incomparability of a pair of bipartite pure entangled states can\nbe established.",
