Abstract:

In this paper, we propose a one-step scheme for implementing the nonadiabatic holonomic SWAP gate with Rydberg atoms. By applying invariant-based reverse engineering to design the effective Hamiltonian of the system, a suitable evolution path for implementing nonadiabatic holonomic quantum computation is found. In addition, the systematic-error-sensitivity nullified optimal control method is considered in the parameter selections, so that the scheme is insensitive to the systematic error of pulses. We also estimate the effects of random noise, the random initial phase of the pulses, the Doppler shift, and decoherence on the scheme. The numerical results show that the scheme exhibits fairly good performance against these negative factors. Finally, we generalize the scheme to realize the non-Clifford SWAP gates. Therefore, this scheme can provide a feasible framework for implementing high-fidelity and robust SWAP gates and non-Clifford SWAP gates with Rydberg atoms.
