Mølmer-Sørensen gates in trapped-ions chains in the presence of correlated noise
D. V. Donchenko, E. A. Anikin, O. Lakhmanskaya +1
We analyze the impact of correlated laser frequency noise on Mølmer-Sørensen gates in qubit registers based on trapped-ion chains. Using perturbation theory, we calculate gate fide…

Fast Mølmer-Sørensen gates in trapped-ion quantum processors with compensated carrier transition
Evgeny Anikin, Andrey Chuchalin, Nikita Morozov +2
Carrier transition is one of the major factors hindering the high-speed implementation of the Mølmer-Sørensen gates in trapped-ion quantum processors. We present an approach to des…
