Abstract
Single neutral atoms trapped in optical tweezers and laser-coupled to Rydberg states provide a fast and flexible platform to generate configurable atomic arrays for quantum simulation. The platform is especially suited to study quantum spin systems in various geometries. However, for experiments requiring continuous trapping, inhomogeneous light shifts induced by the trapping potential and temperature broadening impose severe limitations. Here we show how Raman sideband cooling allows one to overcome those limitations, thus, preparing the stage for Rydberg dressing in tweezer arrays.
Author comments upon resubmission
Thank you for the correspondence and the reports on our manuscript. Below we detail the changes made in response to the referee reports.
Sincerely yours,
The Authors
List of changes
- We added references [42, 44, 45] where the weak dressing equations are introduced.
- We added a more detailed discussion about the hole in the objective and its effects on imaging and tweezer generation. This is indeed a novelty introduced by our setup.
- We now use scientific notation for the numbers in the figure captions.
- We clarified the description of the Raman beam polarizations, also adding arrows indicating the polarization in fig 1.
- We added the missing theory prediction in fig. 4a
- The ratio of the red and blue sideband strengths was inverted before. This is now corrected.
