    "abstract": "We solve the problem of the temporal evolution of one of two-modes embedded\nin a same dissipative environment and investigate the role of the losses after\nthe preparation of a coherent state in only one of the two modes. Based on\ncurrent cavity QED technology, we present a calculation of the fidelity of a\nsuperposition of coherent states engineered in a bimodal high-Q cavity. Our\ncalculation demonstrates that the engineered superposition retains coherence\nfor large times when the mean photon number of the prepared mode is on the\norder of unity.",
