On the local equivalence of trapped-ion two-qudit gates
Nikita V. Semenin, Pavel A. Kamenskikh, Ilia V. Zalivako +2
We derive a necessary condition of the local equivalence between two-qudit gates in terms of singular values of transformed gate matrices. This condition is valid for arbitrary qud…
Analysis of the action of conventional trapped-ion entangling gates in qudit space
Pavel Kamenskikh, Nikita Semenin, Ilia Zalivako +4
Qudits, or multi-level quantum information carriers, present a promising path for scaling quantum computers. However, their use introduces increased complexity in quantum logic, ne…
Supervised binary classification of small-scale digit images and weighted graphs with a trapped-ion quantum processor
Ilia V. Zalivako, Alexander I. Gircha, Evgeniy O. Kiktenko +14
Here we present the results of benchmarking a quantum processor based on trapped Yb ions by performing basic quantum machine learning algorithms. Using a quantum-enha…
Multiqubit GHZ state preparation with ions for frequency standards
A. E. Korolkov, I. V. Zalivako, A. S. Borisenko +5
Multiqubit Greenberger-Horne-Zeilinger (GHZ) state preparation is demonstrated on two to eight qubits in the chain of ten ions in the linear Paul trap with a sequence…
