摘要
The doorway mechanism in which a distinct state is coupled to a background is encountered in a rich variety of systems. Similar scenarios are likely to be relevant in quantum information theory. We review recent analytical and numerical results obtained for various statistical observables: the distribution of the maximum overlap coefficient between doorway and the true eigenstates of the total Hamiltonian, the averaged fidelity which equals survival probability, and the distribution of fidelity.
