Non-adiabatic quantum state preparation and quantum state transport in chains of Rydberg atoms
New Journal of Physics, 2017 Motivated by recent progress in the experimental manipulation of cold atoms in optical lattices, we study three different protocols for non-adiabatic quantum state preparation and state transport in chains of Rydberg atoms.

Dynamical Collective Excitations and Entanglement of Two Strongly Correlated Rydberg Superatoms
Photonics, 2022 Based on the dipole blockade effect and with the aid of the superatom (SA) model, we propose a scheme to investigate the correlated evolution of two Rydberg sub-superatoms (SSAs), formed by two spatially separated atomic Rydberg sub-ensembles but in the ...

Quantifying the impact of state mixing on the Rydberg excitation blockade
Physical Review Research, 2020 The Rydberg excitation blockade has been at the heart of an impressive array of recent achievements; however, state-mixing interactions can compromise its efficiency.

Transport on flexible Rydberg aggregates using circular states
, 2018 Assemblies of interacting Rydberg atoms show promise for the quantum simulation of transport phenomena, quantum chemistry and condensed matter systems. Such schemes are typically limited by the finite lifetime of Rydberg states.

Microwave-Controlled Spectroscopy Evolution for Different Rydberg States
PhotonicsIn this paper, a series of electromagnetically-induced-transparent (EIT) spectra of different Rydberg states, controlled by microwaves, in rubidium (Rb) thermal vapor are presented. The novel evolution regularity for different Rydberg states can be found

Optimizing the fast Rydberg quantum gate [PDF]
, 2002 The fast phase gate scheme, in which the qubits are atoms confined in sites of an optical lattice, and gate operations are mediated by excitation of Rydberg states, was proposed by Jaksch et al. Phys. Rev. Lett. 85, 2208 (2000).

Microwave-optical coupling via Rydberg excitons in cuprous oxide
Physical Review Research, 2022 We report exciton-mediated coupling between microwave and optical fields in cuprous oxide (Cu_{2}O) at low temperatures. Rydberg excitonic states with principal quantum number up to n=12 were observed at 4 K using both one-photon (absorption) and two ...

Phonon dressing of a facilitated one-dimensional Rydberg lattice gas
SciPost Physics Core, 2022 We study the dynamics of a one-dimensional Rydberg lattice gas under facilitation (anti-blockade) conditions which implements a so-called kinetically constrained spin system.

Coincidence spectroscopy of high-lying Rydberg states produced in strong laser fields
, 2016 We report on the measurement of electron emission after the interaction of strong laser pulses with atoms and molecules. These electrons originate from high-lying Rydberg states with quantum numbers up to $n \lesssim 120$ formed by frustrated field ...
