The role of error amplitude in our analysis is played by the product of the elementary gate time t_0 and the spectral width of the interaction Hamiltonian between system and bath. We discuss extensions of our model and the applicability of our analysis.19 pages+ 3 figures; v2: minor corrections and reply to comment by Alicki (http://arxiv.org/abs/quant-ph/0402139)Quantum Physicstext
