Education and careerEdit


Kenji Ohmori has succeeded in designing and visualizing spatiotemporal images given by the interference of matter waves of atoms in a molecule with picometer and femtosecond resolution [1,2]. The precision of this processing is the highest to date, higher than that of the current nanotechnology by three orders of magnitudes. This ultrahigh-precision processing has been implemented with the temporal oscillations of laser electric fields engineered with attosecond precision and imprinted on the matter waves of atoms and electrons in a molecule. He has utilized this technique to develop a molecular computer in which a single 0.3-nanometer-size molecule can calculate 1000 times faster than the current fastest supercomputer [3,4]. He has also developed an ultrafast quantum simulator that can simulate non-equilibrium dynamics of quantum many-body systems in one nanosecond, introducing a novel concept where he has combined his ultrafast coherent control with attosecond precision and ultracold atoms cooled down to temperatures close to absolute zero[5].
