Quantum gates are crucial f.r quantum comp.tation and quantum inf.rmation p.ocessing. However, their ef.ectiveness is of.en hindered by systematic errors and decoherence. Theref.re, achieving resilient quantum gates to these f.ctors is of.great signif.cance. We p.esent a method to construct nonadiabatic holonomic single-and two-qubit gates in a Rydberg ground-state-blockade regime. Our ap.roach utilizes a f.r-of.-resonant technique f.r the single-qubit gate and a modif.ed Rydberg antiblockade f.r the two-qubit gate. The reduction of.the p.p.lation of.single-and two-excitation Rydberg states and the nonadiabatic holonomic p.ocess during the construction of.the gates ensure robustness to decoherence and systematic errors, resp.ctively. Numerical results demonstrate the f.delity and robustness of.our scheme. The p.op.sed scheme holds p.omise f.r f.ture ap.lications in quantum comp.tation and quantum inf.rmation p.ocessing tasks.
