| contents | Environmental noises cause the relaxation of quantum systems and decrease the precision of operations. Apprehending the relaxation mechanism via environmental noises is essential for building quantum technologies. Relaxations can be considered a process of information dissipation from the system into an environment with infinite degrees of freedom (DoF). According to this idea, a model of artificial relaxation has been proposed and demonstrated in NMR experiments. Although this model successfully understood the central idea of relaxation, we observed recursive behavior, which is non-ideal to describe relaxation, because of few DoF of the ``artificial environment''. In this paper, we extend the approach of the artificial environment and discuss, theoretically and experimentally, how many DoF of the environment are necessary for realizing ideal relaxation behavior. Our approach will help us thoroughly understand the concept of relaxation. |
