Abstract Nonadiabatic holonomic quantum computation has attracted increasing interest because of its robustness. Here, based on the shortcuts to adiabaticity, a scheme to construct a three‐qubit nonadiabatic holonomic gate in a cavity quantum electrodynamics system is proposed. In the scheme, the three‐qubit holonomic gate is implemented in a single step. In addition, by numerical simulations, it is shown that the constructed holonomic quantum gate holds characteristics such as high fidelity, decoherence‐resistance, and error‐immunity.
