Outline of Final Research Achievements

Electronic functional elements are usually constituted in the solid state. Quantum computer is kept near absolute zero temperature (-273 degrees Celsius). This is because the quantum state of microscopic particles such as electrons is so fragile that it relaxes under the thermal noise due to large and rapid atomic motions and that the function due to the quantum state does not maintain. In the present study, a dye molecule was introduced into a nanometer-sized reverse micelle, and its optical response was examined by persistent hole-burning spectroscopy. It has been demonstrated that the relaxation of the electronic state of the dye molecule is suppressed owing to the nanoconfinement regardless of the presence of thermal noise in liquids at room temperature. This result suggests the possibility of novel functional nano-elements and provides one way to clarify the quantum-mechanical effect on biological reactions.
