Anastasiia S. Nikolaeva, Ilia V. Zalivako, Alexander S. Borisenko +8
An efficient implementation of the Toffoli gate is of conceptual importance for running various quantum algorithms, including Grover's search and Shor's integer factorization. Howe…
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…
Towards multiqudit quantum processor based on a Yb ion string: Realizing basic quantum algorithms
Ilia V. Zalivako, Anastasiia S. Nikolaeva, Alexander S. Borisenko +12
We demonstrate a quantum processor based on a 3D linear Paul trap that uses Yb ions with 8 individually controllable four-level qudits (ququarts), which is computatio…
