    "abstract": "This is an English translation of the manuscript which appeared in\nSurikaiseki Kenkyusho Kokyuroku No. 1055 (1998). The asymptotic efficiency of\nstatistical estimate of unknown quantum states is discussed, both in adaptive\nand collective settings. Aaptive bounds are written in sigle letterized form,\nand collective bounds are written in limitting expression. Our arguments\nclarify mathematical regularity conditions.",
