【 摘 要 】

The present status of the development of our code, QEDynamics, is reported. In this code, the time evolution simulation is carried out for Heisenberg operators based on quantum electrodynamics in a manner of quantum field theory. For this simulation, the treatment of the photon is important, particularly infrared and ultra-violet photons. As a result, renormalization is one of essential ingredients, since quantum field theory is adopted.
