  Based on a `shortcut-to-adiabaticity' (STA) scheme, we theoretically design
and experimentally realize a set of high-fidelity single-qubit quantum gates in
a superconducting Xmon qubit system. Through a precise microwave control, the
qubit is driven to follow a fast `adiabatic' trajectory with the assistance of
a counter-diabatic field and the correction of derivative removal by adiabatic
gates. The experimental measurements of quantum process tomography and
interleaved randomized benchmarking show that the process fidelities of our STA
quantum gates are higher than 94.9% and the gate fidelities are higher than
99.8%, very close to the state-of-art gate fidelity of 99.9%. An alternate of
high-fidelity quantum gates is successfully achieved under the STA protocol.
