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…
Detection states of ions in a Paul trap via conventional and quantum machine learning algorithms
Ilia Khomchenko, Andrei Fionov, Artem Alekseev +4
Trapped ions are among the leading platforms for quantum technologies, particularly in the field of quantum computing. Detecting states of trapped ions is essential for ensuring hi…
Magnetic field evolution of accreting neutron stars
Ya. N. Istomin, I. A. Semerikov
The flow of a matter, accreting onto a magnetized neutron star, is accompanied by an electric current. The closing of the electric current occurs in the crust of a neutron stars in…
