    "abstract": "A remarkable theorem by Clifton, Bub and Halvorson (2003)(CBH) characterizes\nquantum theory in terms of information--theoretic principles. According to Bub\n(2004, 2005) the philosophical significance of the theorem is that quantum\ntheory should be regarded as a ``principle\u0027\u0027 theory about (quantum) information\nrather than a ``constructive\u0027\u0027 theory about the dynamics of quantum systems.\nHere we criticize Bub\u0027s principle approach arguing that if the mathematical\nformalism of quantum mechanics remains intact then there is no escape route\nfrom solving the measurement problem by constructive theories. We further\npropose a (Wigner--type) thought experiment that we argue demonstrates that\nquantum mechanics on the information--theoretic approach is incomplete.",
