Sub-Doppler laser cooling and optical transport of cesium with static magnetic fields
Tobias Bothwell, Junxin Chen, Brian M. Fields +16
Laser cooling of alkali atoms typically requires time-varying magnetic fields, introducing unwanted coupling between atom preparation and coherent operations. Here we demonstrate s…
Demonstration of a Logical Architecture Uniting Motion and In-Place Entanglement
Rich Rines, Benjamin Hall, Mariesa H. Teo +35
We demonstrate a logical neutral atom architecture that integrates atom motion with in-place entanglement to achieve lower overheads than entangling-zone approaches. Using a 114-qu…
Atomic clock frequency ratios with fractional uncertainty
Alexander Aeppli, Willa J. Arthur-Dworschack, Kyle Beloy +24
We report high-precision frequency ratio measurements between optical atomic clocks based on Al, Yb, and Sr. With total fractional uncertainties at or bel…
Blackbody radiation Zeeman shift in Rydberg atoms
K. Beloy, B. D. Hunt, R. C. Brown +5
We consider the Zeeman shift in Rydberg atoms induced by room-temperature blackbody radiation (BBR). BBR shifts to the Rydberg levels are dominated by the familiar BBR Stark shift.…
Cryogenic Optical Lattice Clock with Blackbody Radiation Stark Uncertainty
Youssef S. Hassan, Kyle Beloy, Jacob L. Siegel +9
Controlling the Stark perturbation from ambient thermal radiation is key to advancing the performance of many atomic frequency standards, including state-of-the-art optical lattice…
