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…
Opportunities for DOE National Laboratory-led QuantISED Experiments
Pete Barry, Karl Berggren, A. Baha Balantekin +24
A subset of QuantISED Sensor PIs met virtually on May 26, 2020 to discuss a response to a charge by the DOE Office of High Energy Physics. In this document, we summarize the QuantI…
Optical Atomic Clock Comparison through Turbulent Air
Martha I. Bodine, Jean-Daniel Deschênes, Isaac H. Khader +32
We use frequency comb-based optical two-way time-frequency transfer (O-TWTFT) to measure the optical frequency ratio of state-of-the-art ytterbium and strontium optical atomic cloc…
Frequency Ratio Measurements with 18-digit Accuracy Using a Network of Optical Clocks
Boulder Atomic Clock Optical Network, Collaboration, : +35
Atomic clocks occupy a unique position in measurement science, exhibiting higher accuracy than any other measurement standard and underpinning six out of seven base units in the SI…
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…
