\nWe finished a thorough analysis on the effect of laser noise on 1- a nd 2-photon Rabi oscillations\, with both theoretical analysis and num erical simulations. We developed a theory to directly match a laser's frequency noise power spectral density to its self-heterodyne spectrum measured in labs. We also predicted the error generated by white nois e and spectrums with servo-bumps\, and our results have a good match w ith numerical simulations. A quasi-static theory is also proposed to e stimate the error under certain limits\, and has demonstrated good mat ch with the numerics.

\nWe design a protocol for multi-qubi t neutral atom gates. The protocol implements symmetric adiabatic puls es on the k+1 atoms in the system to implement CkZ gates and CZk gates . Equal Rydberg coupling strengths between all qubits are needed for C kZ gates\, and zero coupling between target qubits is needed for CZk g ates. We show that fidelity F >\;0.99 can be achieved for both type of gates\, with gate times ~0.5 μs for k<\;=4. Our analysis is perf ormed with experimentally realistic parameters.
