Query: Dissipative dynamics of a driven qubit: interplay between non-adiabatic
  dynamics and noise effects from weak to strong coupling regime   We study the exact solution of the Schr\"odinger equation for the dissipative
dynamics of a qubit, achieved by means of Short Iterative Lanczos method (SIL),
which allows us to describe the qubit and the bath dynamics from weak to strong
coupling regimes. We focus on two different models of a qubit in contact with
the external environment: the first is the Spin Boson Model (SBM), which gives
a description of the qubit in terms of static tunnelling energy and a bias
field. The second model describes an externally driven qubit, where both the
bias field and the tunnelling rate are controlled by a time-dependent magnetic
field obeying to a finite time protocol. We show that in the SBM case, our
solution correctly describes the crossover from coherent to incoherent behavior
of the magnetization, occurring at the Toulouse point. Furthermore, we show
that the bath response dramatically changes during the system dynamics, going
from non-resonant at small times to resonant behavior at long times. When the
external driving field is present, for fixed values of the drive duration our
results show that the bath can provide beneficial effects to the success of the
protocol. We find evidence for a complex interplay between non-adiabaticity of
the protocol due to the external drive and dissipation effects, which strongly
depends on the detailed form of the qubit-bath interaction.
