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…
Atomic Coherence of 2 minutes and Instability of 1.5E-18 at 1 s in a Wannier-Stark Lattice Clock
Kyungtae Kim, Alexander Aeppli, William Warfield +3
We explore the limits of atomic coherence and measurement precision in a 87Sr optical lattice clock. We perform a detailed characterization of key effects, including lattice Raman…
High-Stability Single-Ion Clock with Systematic Uncertainty
Mason C. Marshall, Daniel A. Rodriguez Castillo, Willa J. Arthur-Dworschack +10
We report a single-ion optical atomic clock with fractional frequency uncertainty of and fractional frequency stability of $3.5 \times10^{-16}/\sqrt{τ/\mathrm{s…
A High-Power Clock Laser Spectrally Tailored for High-Fidelity Quantum State Engineering
Lingfeng Yan, Stefan Lannig, William R. Milner +5
Highly frequency-stable lasers are a ubiquitous tool for optical frequency metrology, precision interferometry, and quantum information science. While making a universally applicab…
