    "abstract": "The quantum analogues of classical variable-length codes are\nindeterminate-length quantum codes, in which codewords may exist in\nsuperpositions of different lengths. This paper explores some of their\nproperties. The length observable for such codes is governed by a quantum\nversion of the Kraft-McMillan inequality. Indeterminate-length quantum codes\nalso provide an alternate approach to quantum data compression.",
