| Research Abstract |
The ability to control molecular wave functions may lead to novel quantum technologies such as bond-selective chemistry and quantum computing. An understanding of the coherent loss process is essential for the realization of these quantum technologies using quantum interference effects in condensed media. Although the overwhelming majority of chemical reactions take place in solution, there have been very few experimental studies on the coherent reaction control of polyatomic molecules in condensed media, due to the rapid decoherence of wavefunctions. These fast quantum-phase relaxations are thought to be caused by solute-solvent interactions. Thus, an understanding of the roles of solvent molecules in the dephasing mechanism is strongly required. It is noted that the inhibition of dephasing is necessary for the development of coherent control techniques for more general reactions. Therefore, the protection of molecular wavefunctions from the surrounding environment becomes an important issue for the realization of quantum control techniques in condensed phases.
