Autoionization of Ultracold Cesium Rydberg Atom in 37D5/2 State
Photonics, 2022 We present the observation of an autoionization of cesium 37D5/2 Rydberg atoms in ultracold gases and analyze the autoionization mechanism. The autoionization process is investigated by varying the delay time tD and Rydberg atomic density. The dependence

Floquet-tailored Rydberg interactions
Nature Communications, 2023 The Rydberg blockade is a key ingredient for entangling atoms in arrays. However, it requires atoms to be spaced well within the blockade radius, which limits the range of local quantum gates.

One-Step Implementation of Collective Anti-Blockade in a Rydberg Ring
Photonics, 2023 In contrast to Rydberg blockade, Rydberg anti-blockade allows multiple atoms to be simultaneously excited in the presence of significant nonlocal interactions and can lead to distinct phenomena and applications.

Observation of a molecular bond between ions and Rydberg atoms [PDF]
Nature, 2021 Atoms with a highly excited electron, called Rydberg atoms, can form unusual types of molecular bonds1–4. The bonds differ from the well-known ionic and covalent bonds5,6 not only by their binding mechanisms, but also by their bond lengths ranging up to ...

Deep learning enhanced Rydberg multifrequency microwave recognition
Nature Communications, 2022 Rydberg atoms are sensitive to microwave signals and hence can be used to detect them. Here the authors demonstrate a Rydberg receiver enhanced by deep learning, Rydberg atoms acting as antennae, to receive, extract, and decode the multi-frequency ...

Resilient quantum gates on periodically driven Rydberg atoms [PDF]
Physical Review A, 2021 Fault-tolerant implementation of quantum gates is one of preconditions for realizing quantum computation. The platform of Rydberg atoms is one of the most promising candidates for achieving quantum computation.

Trapping of Rydberg Atoms in Tight Magnetic Microtraps [PDF]
, 2018 We explore the possibility to trap Rydberg atoms in tightly confining magnetic microtraps. The trapping frequencies for Rydberg atoms are expected to be influenced strongly by magnetic field gradients.
