    "abstract": "In this paper, we give another proof of quantum Stein\u0027s lemma by calculating\nthe information spectrum, and study an asymptotic optimal measurement in the\nsense of Stein\u0027s lemma. We propose a projection measurement characterized by\nthe irreducible representation theory of the special linear group SL(H).\nSpecially, in spin 1/2 system, it is realized by a simultaneous measurement of\nthe total momentum and a momentum of a specified direction.",
