Excitation spectrum of a multilevel atom coupled with a dielectric nanostructure
N. A. Moroz, L. V. Gerasimov, A. D. Manukhova +1
We develop a microscopic calculation scheme for the excitation spectrum of a single-electron atom localized near a dielectric nanostructure. The atom originally has an arbitrary de…
Spatial dependence of fidelity for a two-qubit Rydberg-blockade quantum gate
Ivan Vybornyi, Leonid Gerasimov, Dmitriy Kupriyanov +2
We study the spatial performance of the entangling gate proposed by H. Levine et al. (Phys. Rev. Lett. 123, 170503 (2019)). This gate is based on a Rydberg blockade technique and c…
Coupled dynamics of spin qubits in optical dipole microtraps
L. V. Gerasimov, R. R. Yusupov, A. D. Moiseevsky +6
Single atoms in dipole microtraps or optical tweezers have recently become a promising platform for quantum computing and simulation. Here we report a detailed theoretical analysis…
Dynamics of a spin qubit in an optical dipole trap
L. V. Gerasimov, R. R. Yusupov, I. B. Bobrov +5
We present a theoretical investigation of coherent dynamics of a spin qubit encoded in hyperfine sublevels of an alkali-metal atom in a far off-resonant optical dipole trap. The qu…
Single collective excitation of an atomic array trapped along a waveguide: a study of cooperative emission for different atomic chain configurations
V. A. Pivovarov, L. V. Gerasimov, J. Berroir +4
Ordered atomic arrays trapped in the vicinity of nanoscale waveguides offer original light-matter interfaces, with applications to quantum information and quantum non-linear optics…
Quantum interface between light and a one-dimensional atomic system
Viacheslav A. Pivovarov, Alexandra S. Sheremet, Leonid V. Gerasimov +2
We investigate optimal conditions for the quantum interface between a signal photon pulse and one-dimensional chain consisting of a varied number of atoms. The tested object is phy…
