Abstract
We summarize our results on decoherence for short-to intermediate-time dynamics of an externally controlled two-state quantum system—a qubit—interacting with thermal bosonic environment. The developed approximation schemes are illustrated for an adiabatic model with time-dependent gate control, and for a model with rotating-wave gate function.
