Many of the phenomena around us, such as the Standard Model of elementary particles, are described in terms of quantum field theory. Understanding the physics of the microscopic realm is important not only for investigating the ultimate constituents of matter, but also for exploring the nature of quantum many-body systems, in which many fundamental quantum systems cooperate with each other to create new physical phenomena. The goal of group D01 is to elucidate the dynamics of matter that exhibits such quantum behavior. In quantum information theory, how quantum systems change under various physical manipulations is investigated from a general viewpoint. By adopting the perspective of quantum information theory, new aspects of quantum field theory may be revealed that cannot be understood by conventional methods. In particular, by focusing on the common mathematical structure behind quantum field theory and quantum information theory, we hope to uncover universal properties that all field quantum theories should possess, independent of individual quantum systems. As a complementary approach to examining the dynamics of quantum field theories, we will perform quantum computer simulations of quantum field theories. Many physical systems, including finite density systems and real time systems, are difficult to simulate on classical computers, but are expected to be efficiently simulated on quantum computers. By developing and implementing methods of quantum computation suitable for quantum field theory, we will be able to elucidate important phenomena such as the scattering process of elementary particles and the evaporation process of black holes. Furthermore, we will explore the relationship between the quantum information theory aspect of quantum field theory and holographic principles as well as quantum gravity theory.<\/p>\n
