Impact of qubit anharmonicity on near-resonant Rabi oscillations
Grigoriy S. Mazhorin, Andrei A. Kugut, Artyom M. Polyanskiy +2
Precise quantum control relies on a deep understanding of the dynamics of quantum systems under external drives. This study investigates the impact of anharmonicity on qubit dynami…
