Experimental characterization of the Toffoli gate via channel spectrum benchmarking
D. K. Korliakov, B. I. Bantysh, A. S. Borisenko +2
Channel spectrum benchmarking (CSB) provides a robust framework for characterizing quantum gate fidelities while remaining insensitive to state preparation and measurement (SPAM) e…

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…

Experimental factoring integers using fixed-point-QAOA with a trapped-ion quantum processor
Ilia V. Zalivako, Andrey Yu. Chernyavskiy, Anastasiia S. Nikolaeva +10
Factoring integers is considered as a computationally-hard problem for classical methods, whereas there exists polynomial-time Shor's quantum algorithm for solving this task. Howev…
