Biography

I am a postdoctoral researcher at Center for Quantum Information and Quantum Biology (QIQB), Osaka University. After obtaining a PhD in condensed matter experiment, I worked on computational studies of correlated electron systems. Now I study application of quantum computation to solving quantum many-body problems, etc.
