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…
Zeno and Anti-Zeno Effects in Dark-State Dynamics Under Thermal Dephasing: A Numerical Study
Ran Chen, Jiangchuan You, Alexey Vladimirovich Kulagin +2
The quantum Zeno and anti-Zeno effects describe how frequent measurements can either suppress or accelerate quantum dynamics. While extensively studied in various platforms, their…
Influence of environment on quantum correlations in two-spin systems with dipole-dipole interactions
G. A. Bochkin, E. B. Fel'dman, E. I. Kuznetsova +1
An influence of environment on quantum correlations (entanglement and quantum discord) is studied in a two-spin-1/2 system with dipole-dipole interactions on the basis of Lindblad…
Optical nonlinearity of cold atomic ensemble driven by strong coherent field in a saturation regime
A. S. Usoltsev, L. V. Gerasimov, A. D. Manukhova +2
We present a microscopic analysis and evaluation of the dielectric susceptibility of a dielectric medium consisting of vector-type two-energy-level atoms responding on a weak probe…
Quantum electrodynamic description of ionization of the neutral hydrogen molecule
Hui-hui Miao
We investigate hydrogen molecule ionization within a unified framework combining finite-dimensional quantum electrodynamics with the Lindblad master equation, enabling systematic c…
