Outline of Final Research Achievements

In the last decade, the direct control of quantum wave functions of molecular electronic and vibrational states has been developed in the areas pf coherent control of chemical reactions and quantum computing by using ultrafast femtosecond laser. For the achievment of quantum control, the suppression of decohrence of wavefunctions are obviously important. Therefore, we studied the decohrence process of molecular wavefunctions of polycondensed aromatic molecules in the cyclodextrin nanocavity in aqueous/alcohol or aqueous/keton solvents with the deconvolution method by using Voigt function fitting. We also studied fluctuation of polymers motions in aqueous solution by using molecular dynamics simulations.
