Abstract
Decoherence of two-state systems due to superohmic damping, which is obtained in Josephson junctions made by high-Tc superconductors, is numerically studied by a quantum Monte Carlo method. By calculating a dynamical structure factor, we demonstrate a coherent-incoherent crossover by controlling both damping strength and temperature.
