Query: Quantum speed-up based on classical-field and moving-qubit   In this work, we provide a model of a moving-qubit interacting with the
multimode cavity, where the qubit is driven by the classical field. We obtain
the analytic solution of the density operator of the qubit, then investigate
the quantum speed limit time(QSLT) and the non-Markovianity based on the
classical field and the moving-velocity. The results show that the transition
from Markovian to non-Markovian dynamics is the intrinsic physical reason of
the quantum speed-up process, both of the driving field and the strong coupling
can enhance the non-Markovianity in the dynamics process and speed up the
evolution of the qubit, but the moving velocity of the qubit can decrease the
non-Markovianity in dynamics process and delay the evolution of qubit. To some
extent, the classical field can reduce the effect of the moving velocity of the
qubit on the quantum evolution process.
