Fast Entangling Gates for Rydberg Atoms via Resonant Dipole-Dipole Interaction

PRX Quantum
The advent of digital neutral-atom quantum computers relies on the development of fast and robust protocols for high-fidelity quantum operations. In this work, we introduce a novel scheme for entangling gates using four atomic levels per atom: a ground ...

Distributing entanglement at the quantum speed limit in Rydberg chains

Physical Review Research
We numerically study the transport of Rydberg excitations in chains of neutral atoms. We realize an effective flip-flop interaction using off-resonant driving fields.

Rydberg atoms: Correlations and quantum gates

, 2016
In this project, we investigate into the correlations between Rydberg atoms, atoms that are excited to a state of a high principal quantum number and have at least one valence electron, and the interactions that occur between them that can be used for ...

MICROWAVE AND SURFACE ELECTROMETRY WITH RYDBERG ATOMS [PDF]

, 2016
Measurements of microwave electric fields in rubidium vapor cells, and of static electric fields near quartz with cold rubidium are presented. The measurements are performed using electromagnetically induced transparency (EIT) with Rydberg atoms.

Trapping Rydberg Atoms in Ponderomotive Optical Lattices. [PDF]

I examine the trapping of Rydberg atoms in an optical standing wave. This trap, called an optical lattice, offers a platform for utilizing Rydberg atoms and their unique properties in applications such as atomic spectroscopy and quantum computing ...

Spatial Imaging of Strongly Interacting Rydberg Atoms [PDF]

, 2017
The strong interactions between Rydberg excitations can result in spatial correlations between the excitations. The ability to control the interaction strength and the correlations between Rydberg atoms is applicable in future technological ...

Dissociative electron attachment studies with hyperthermal Rydberg atoms

, 2018
Earlier studies of the velocity distributions of heavy-Rydberg ion-pair states formed in collisions between potassium Rydberg atoms with low-to-intermediate values of n, 10 ≲ n ≲ 15, and targets that attach free low-energy electrons have shown that such ...

Observation of effects of inter-atomic interaction on Autler–Townes splitting in cold Rydberg atoms

New Journal of Physics
We demonstrate the effect of inter-atomic interaction in highly excited Rydberg atoms via Autler–Townes (AT) splitting in cold atoms. We measure the AT splitting of the $\{5S_{1/2}, F = 2\} \rightarrow \{5P_{3/2}, F^{^{\prime}} = 3\}$ transition of ^87 ...

Calculation of Rydberg energy levels of rubidium in an electric field [PDF]

, 2008
Energy levels of Rydberg Rubidium atoms in an external electric field are calculated by Hamiltonian-diagonalization and Coulomb approximation. The results are in agreement with previous studies and with the expected scaling laws.

Diffraction of Rydberg atoms by laser light

, 2008
It is shown that semiclassical path representations provide a well-suited framework for the description of the diffraction of Rydberg atoms by laser light.
