Abstract By using shortcuts to adiabatic (STA) method, the proposal is to implement a fast multi‐photon down‐conversion, which can rapidly create 2 N photons from the quantum vacuum based on the counter‐rotating effect of an ultrastrong light–matter coupling. The energy for the produced photons is given by a high‐frequency pump field. The STA method is used to design the driving fields to induce a rapid population transfer. Such an accelerated evolution can restrain the influence of decoherence during the evolution, so as to generate Fock states from vacuum with high fidelities.
