Control of eigenmode localization and coupling anisotropy by multiscan femtosecond laser writing
S. A. Zhuravitskii, N. S. Kostyuchenko, N. N. Skryabin +5
The multiscan method is widely used in femtosecond laser writing of waveguide systems to increase the refractive index contrast and to control the eigenmode shape. Here, we investi…
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…
Spin vs. position conjugation in quantum simulations with atoms: application to quantum chemistry
N. A. Moroz, K. S. Tikhonov, L. V. Gerasimov +4
The permutation symmetry is a fundamental attribute of the collective wavefunction of indistinguishable particles. It makes a difference for the behavior of collective systems havi…
Interaction-Resilient Scalable Fluxonium Architecture with All-Microwave Gates
Andrei A. Kugut, Grigoriy S. Mazhorin, Ilya A. Simakov
Fluxonium qubits demonstrate exceptional potential for quantum processing; yet, realizing scalable architectures using them remains challenging. We propose a fluxonium-based square…
Microring resonator as a Rayleigh mirror for broadband laser-cavity comb generation
Aram A. Mkrtchyan, Anastasia S. Netrusova, Mikhail S. Mishevsky +7
High-quality microring resonators (MRRs) have proven to be promising sources of optical combs generated from continuous-wave radiation. In addition to the primary comb that propaga…
