Scalable quantum logic spectroscopy
Kaifeng Cui, Jose Valencia, Kevin T. Boyce +2
In quantum logic spectroscopy (QLS), one species of trapped ion is used as a sensor to detect the state of an otherwise inaccessible ion species. This extends precision measurement…
Optical coherence between atomic species at the second scale: improved clock comparisons via differential spectroscopy
May E. Kim, William F. McGrew, Nicholas V. Nardelli +9
Comparisons of high-accuracy optical atomic clocks \cite{Ludlow2015} are essential for precision tests of fundamental physics \cite{Safronova2018}, relativistic geodesy \cite{McGre…
Lifetime-Limited Interrogation of Two Independent Clocks Using Correlation Spectroscopy
E. R. Clements, M. E. Kim, K. Cui +7
Laser decoherence limits the stability of optical clocks by broadening the observable resonance linewidths and adding noise during the dead time between clock probes. Correlation s…
Measurements of Al and Mg magnetic constants for improved ion clock accuracy
S. M. Brewer, J. -S. Chen, K. Beloy +14
We have measured the quadratic Zeeman coefficient for the optical clock transition in Al, ~MHz/T, an…
Systematic uncertainty due to background-gas collisions in trapped-ion optical clocks
A. M. Hankin, E. R. Clements, Y. Huang +5
We describe a framework for calculating the frequency shift and uncertainty of trapped-ion optical atomic clocks caused by background-gas collisions, and apply this framework to an…
