Single Atoms with 6000-Second Trapping Lifetimes in Optical-Tweezer Arrays at Cryogenic Temperatures
Open accessAbstract
We report on the trapping of single $\mathrm{Rb}$ atoms in tunable arrays of optical tweezers in a cryogenic environment at approximately 4 K. We describe the design and construction of the experimental apparatus, based on a custom-made UHV-compatible closed-cycle cryostat with optical access. We demonstrate the trapping of single atoms in cryogenic arrays of optical tweezers, with lifetimes up to 6000 s, despite the fact that the vacuum system has not been baked out. These results open the way to large arrays of single atoms with extended coherence, for applications in large-scale quantum simulation of many-body systems and, more generally, in quantum science and technology.

Cooling the experimental setup to about 4 K can yield trap lifetimes of up to 6000 s.
“when cooling the experimental setup to about 4 K, trap lifetimes of up to 6000 s have been observed in experiments [39].”
From Neutral atom quantum computing hardware: performance and end-user perspective (2023) · cites this paper as [39]
Cooling the setup can greatly reduce black-body radiation-induced transitions in Rydberg atoms.
“The latter can also be greatly reduced by cooling of the setup, since the black-body radiation intensity scales as T 4 [39].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
