Rydberg Laser Tuning Reduces Gate Infidelity Across Frequencies

6/17/2026

Summary

Story summary

Researchers tuned a Rydberg laser perpendicular to the quantization axis.
The laser sat between two Zeeman-split transitions, giving ?± components an 8 MHz detuning.
Simulations assumed an 88 µs Rydberg lifetime and a light-shift coefficient of 0.945 MHz/MHz².
Researchers plotted infidelity curves for nominal Rabi frequencies of 2, 4, 8, 12 and 16 MHz.
Researchers used AR gates with a single-photon transition, TO gates with two-photon light shifts, and zones of 30, 50 and 70 µm at 75 W.
