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-…
Mitigating Quantum Gate Errors for Variational Eigensolvers Using Hardware-Inspired Zero-Noise Extrapolation
Alexey Uvarov, Daniil Rabinovich, Olga Lakhmanskaya +3
Variational quantum algorithms have emerged as a cornerstone of contemporary quantum algorithms research. Practical implementations of these algorithms, despite offering certain le…
Individual addressing of ion qubits with counter-propagating optical frequency combs
Evgeny Anikin, Lianna A. Akopyan, Mikhail Popov +3
We propose a new method of individual single-qubit addressing of linear trapped-ion chains utilizing two ultrastable femtosecond frequency combs. For that, we suggest implementing…
Surface trap with adjustable ion couplings for scalable and parallel gates
