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…
Decay Rates in 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…
Realization of a Quantum Error Detection Code with a Dynamically Reassigned Ancillary Qubit
Alena S. Kazmina, Artyom M. Polyanskiy, Elena Yu. Egorova +5
Quantum error correction (QEC) is essential for achieving fault-tolerant quantum computing. While superconducting qubits are among the most promising candidates for scalable QEC, t…
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…
