Two-photon Doppler-free spectroscopy of the Rydberg transition for quantum sensing in ytterbium

Benjamin D. Hunt, Kyle Beloy, Roger C. Brown +5

Here we report atomic structure calculations and experimental observations of the two-photon transition in Yb. The unique level structure of…

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…

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…

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…

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…

Deployment of a Transportable Yb Optical Lattice Clock

Tobias Bothwell, Wesley Brand, Robert Fasano +16

We report on the first deployment of a ytterbium (Yb) transportable optical lattice clock (TOLC), commercially shipping the clock 3,000 km from Boulder, Colorado to Washington DC.…

Lattice Light Shift Evaluations In a Dual-Ensemble Yb Optical Lattice Clock

Tobias Bothwell, Benjamin D. Hunt, Jacob L. Siegel +9

In state-of-the-art optical lattice clocks, beyond-electric-dipole polarizability terms lead to a break-down of magic wavelength trapping. In this Letter, we report a novel approac…

Ratchet Loading and Multi-Ensemble Operation in an Optical Lattice Clock

Youssef S. Hassan, Takumi Kobayashi, Tobias Bothwell +6

We demonstrate programmable control over the spatial distribution of ultra-cold atoms confined in an optical lattice. The control is facilitated through a combination of spatial ma…
