    "abstract": "We derive the optimal exponent of the error probability of the quantum\nfixed-length pure state source coding in both cases of blind coding and visible\ncoding. The optimal exponent is universally attained by Jozsa et al. (PRL, 81,\n1714 (1998))\u0027s universal code. In the direct part, a group representation\ntheoretical type method is essential. In the converse part, Nielsen and Kempe\n(PRL, 86, 5184 (2001))\u0027s lemma is essential.",
