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.

Trapping potentials and quantum gates for microwave-dressed Rydberg atoms on an atom chip

Physical Review Research
Rydberg atoms in dc electric fields acquire static dipole moments. When the atoms are close to a surface producing an inhomogeneous electric field, such as by the adsorbates on an atom chip, depending on the sign of the dipole moment of the Rydberg-Stark

Stochastic series expansion quantum Monte Carlo for Rydberg arrays

SciPost Physics Core
Arrays of Rydberg atoms are a powerful platform to realize strongly-interacting quantum many-body systems. A common Rydberg Hamiltonian is free of the sign problem, meaning that its equilibrium properties are amenable to efficient simulation by quantum ...

Scaled-energy spectroscopy of helium M=1 Rydberg atoms in a static electric field. [PDF]

, 1998
We present scaled-energy spectra on helium Rydberg atoms in a static electric field. /M/ = 1 states were studied in excitation from the 2 S-1(0) metastable state.

Isotropic antenna based on Rydberg atoms

Optics Express
Governed by the hairy ball theorem, classical antennas with isotropic responses to linearly polarized radio waves are unrealizable. Also, their calibrations face a causal dilemma. Therefore, radio wave measurements based on classical antennas are challenging to achieve high accuracy.

Quantum computation via Floquet tailored Rydberg interactions

npj Quantum Information
Rydberg atoms have stood out as a highly promising platform for realizing quantum computation. Floquet frequency modulation (FFM), in Rydberg atom systems, provides a unique tool for achieving precise quantum control and uncovering exotic physical ...

-symmetry in Rydberg atoms

, 2016
We propose a scheme to realize parity-time ($\mathcal {PT}$ )-symmetry in an ensemble of strongly interacting Rydberg atoms, which act as superatoms due to the dipole blockade mechanism.

Towards a fictitious magnetic field trap for both ground and Rydberg state 87Rb atoms via the evanescent field of an optical nanofiber

New Journal of Physics
Cold Rydberg atoms, known for their long lifetimes and strong dipole-dipole interactions that lead to the Rydberg blockade phenomenon, are among the most promising platforms for quantum simulations, quantum computation and quantum networks.

Quantum technologies with Rydberg atoms

Frontiers in Quantum Science and Technology
Rydberg atoms have highly controllable exotic properties such as strong inter-atomic interaction, high polarizability, and long lifetimes which enabled unprecedented progress in Rydberg atom-based quantum Technologies. We present a brief review of recent
