    "abstract": "We discuss the cases where local decoherence selectively degrades one type of\nentanglement more than other types. A typical case is called state ordering\nchange, in which two input states with different amounts of entanglement\nundergoes a local decoherence and the state with the larger entanglement\nresults in an output state with less entanglement than the other output state.\nWe are also interested in a special case where the state with the larger\nentanglement evolves to a separable state while the other output state is still\nentangled, which we call selective entanglement breaking. For three-level or\nlarger systems, it is easy to find examples of the state ordering change and\nthe selective entanglement breaking, but for two-level systems it is not\ntrivial whether such situations exist. We present a new strategy to construct\nexamples of two-qubit states exhibiting the selective entanglement breaking\nregardless of entanglement measure. We also give a more striking example of the\nselective entanglement breaking in which the less entangled input state has\nonly an infinitesimal amount of entanglement.",
