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…

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…
