Symmetric C Z gate for ultracold neutral atoms based on counterdiabatic driving at Rydberg excitation
The paper introduces a novel method for implementing a symmetric Controlled-Z (CZ) gate using counterdiabatic driving during Rydberg excitation of neutral atoms. This approach combines adiabatic pulses with counterdiabatic driving to achieve fast gate operation times, bridging the gap between fully adiabatic and time-optimal protocols. The scheme maintains high fidelity while reducing sensitivity to laser intensity variations.
