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…

Lemniscate phase trajectories for high-fidelity GHZ state preparation in trapped-ion chains
Evgeny V. Anikin, Andrey Chuchalin, Dimitrii Donchenko +2
In trapped-ion chains, multipartite GHZ states can be prepared natively with the help of a single bichromatic laser pulse. However, higher-order terms in the expansion in the Lamb-…
