Quantum gates are crucial for quantum computation and quantum information processing.However,their effectiveness is often hindered by systematic errors and decoherence.Therefore,achieving resilient quantum gates to these factors is of great significance.We present a method to construct nonadiabatic holonomic single-and two-qubit gates in a Rydberg ground-state-blockade regime.Our approach utilizes a far-off-resonant technique for the single-qubit gate and a modified Rydberg antiblockade for the two-qubit gate.The reduction of the population of single-and two-excitation Rydberg states and the nonadiabatic holonomic process during the construction of the gates ensure robustness to decoherence and systematic errors,respectively.Numerical results demonstrate the fidelity and robustness of our scheme.The proposed scheme holds promise for future applications in quantum computation and quantum information processing tasks.
