The striking nonlinear effects exhibited by cavity QED systems make them a powerful tool in modern condensed matter and atomic physics. A recently discovered example is the quantized pumping of energy into a cavity by a strongly coupled, periodically (Floquet) driven spin. We uncover a remarkable feature of these energy pumps: they coherently translate, or boost, a quantum state of the cavity in the Fock basis. Furthermore, we argue that the required ultra-strong coupling may be achieved in a rotating frame. Boosting thus enables the preparation of highly excited nonclassical cavity states in near term optical cavity and circuit QED experiments. One need only boost low occupation states.
