Simulations of "Decoherence" with Noise Pulses

Abstract
A simulation of decoherence as random noise in the Hamiltonian is studied. The full Hamiltonian for the rf Squid is used, with the parameters chosen such that there is a double-potential well configuration where the two quasi-degenerate lowest levels are well separated from the rest. The results for these first two levels are in quantitative agreement with expectations from the ``spin 1/2'' picture for the behavior of a two-state system.
