Native CCZ Gate with Fluxonium Qubits and a Microwave-Driven Coupler
Grigoriy S. Mazhorin, Tatyana A. Chudakova, Alena S. Kazmina +12
Native multi-qubit gates could reduce the overhead associated with decompositions into single- and two-qubit operations, but whether they can simultaneously provide high fidelity,…
States dressing analysis in a transmon-transmon-bus system
P. A. Gladilovich, R. A. Migdisov, A. V. Sabluk +5
The multi-qubit gates fidelity of superconducting quantum processors can be limited due to the dressing of computational states by noncomputational ones. Here, we experimentally an…
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…
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…
