Decoherence and loschmidt echoes: Quantum against classical
Some recent theoretical results on the stability of quantum dynamics against perturbations of the Hamiltonian- the so-called Loschmidt echoes and their relation to various decoherence measures are reviewed. We show thatthe representation of Loschmidt echoes in terms of theWigner function can explain...
