Influence of fast and slow laser phase noise on the fidelity of the Mølmer-Sørensen trapped-ion gate

Nikita Semenin, Ksenia Khabarova, Nikolay Kolachevsky

High-fidelity two-qubit entangling gates are essential for the realization of useful quantum algorithms on quantum processors. The Mølmer-Sørensen (MS) gate has become a common cho…

Implementation of two-qubit Rydberg operations on neutral Rb-87 atoms in systems with different intermediate states

I. V. Iukhnovets, O. V. Bychkova, I. B. Bobrov +4

This work presents an experimental setup for implementing two-qubit operations on neutral atoms (Rb) with the possibility of using two different Rydberg excitation schemes.…

Addressable Rydberg excitation in arrays of single neutral atoms with a strongly focused flat-top beam

I. V. Iukhnovets, M. Y. Goloshchapov, A. P. Gordeev +4

We present a method for generating a laser beam with flat intensity and phase profiles in the focal region where the beam interacts with neutral Rb atoms in an array of opti…

Vertical ion transport in a surface Paul trap: escalator and elevator approaches

Alexey Russkikh, Nikita Zhadnov

Surface ion traps confining and manipulating tens of ion qubits have become the leading platform for quantum processors with high quantum volume. These devices employ the Quantum C…

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…
