  We implement a quantum walk in phase space with a new mechanism based on the
superconducting resonator-assisted double quantum dots. By analyzing the hybrid
system, we obtain the necessary factors of realization of a quantum walk in
phase space: the walker, coin, coin flipping and conditional phase shift. In
order to implement the coin flipping operator, we add a driving field to the
resonator. The interaction between the quantum dots and resonator field is used
to implement conditional phase shift. Furthermore, we show with different
driving fields the quantum walk in phase space exhibits a ballistic behavior
over 25 steps and numerically analyze the factors which influence the spreading
of the walker in phase space.
