This study presents the synthesis of polyvinyl acetate (PVAc) by solution polymerization and its partial hydrolysis to polyvinyl alcohol (PVA) using alkaline alcoholysis. The influence of the molar ratio of hydrolysis catalyst (NaOH) to PVAc and the time and temperature of the saponification reaction on the degree of hydrolysis and molecular weight of the PVA were investigated using response su...

Large-scale quantum computation is likely to require massive quantum error correction (QEC). QEC codes and circuits aredescribed via the stabilizer formalism, which represents stabilizer states by keeping track of the operators that preserve them. Suchstates are obtained by stabilizer circuits (consisting of CNOT, Hadamard and Phase only) and can be represented compactly onconventio...

Knill introduced a generalization of stabilizer codes, in this note called Clifford codes. It remained unclear whether or not Clifford codes can be superior to stabilizer codes. We show that Clifford codes are stabilizer codes provided that the abstract error group has an abelian index group. In particular, if the errors are modelled by tensor products of Pauli matrices, then the associated Cli...
