Native CCZ Gate with Fluxonium Qubits and a Microwave-Driven Coupler
Grigoriy S. Mazhorin, Tatyana A. Chudakova, Alena S. Kazmina +12
The paper reports an experimental demonstration of a native three-qubit controlled-controlled-phase (CCZ) gate using fluxonium qubits coupled via a microwave-driven transmon couple…
Interleaved Benchmarking with Single-Qubit References
Ilya A. Simakov, Arina V. Zotova, Tatyana A. Chudakova +10
Cross-entropy benchmarking (XEB) with single-qubit reference sequences is widely used to characterize multi-qubit gates in large-scale quantum processors, despite the lack of a rig…
Interaction-Resilient Scalable Fluxonium Architecture with All-Microwave Gates
Andrei A. Kugut, Grigoriy S. Mazhorin, Ilya A. Simakov
Fluxonium qubits demonstrate exceptional potential for quantum processing; yet, realizing scalable architectures using them remains challenging. We propose a fluxonium-based square…
Towards practical non-Markovianity measures: Normalization and regularization techniques
L. A. Mazhorina, N. D. Korolev, N. V. Morozov +15
Measures characterizing the non-Markovianity degree of the quantum dynamics have several drawbacks when applied to real devices. They depend on the chosen measurement time interval…
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…
Effect of Etching Methods on Dielectric Losses in Transmons
T. A. Chudakova, G. S. Mazhorin, I. V. Trofimov +9
Superconducting qubits are considered as a promising platform for implementing a fault tolerant quantum computing. However, surface defects of superconductors and the substrate lea…
