Direct comparisons of European primary and secondary frequency standards via satellite techniques
F. Riedel, A. Al-Masoudi, E. Benkler +46
We carried out a 26-day comparison of five simultaneously operated optical clocks and six atomic fountain clocks located at INRIM, LNE-SYRTE, NPL and PTB by using two satellite-bas…
Compact laser system for a laser-cooled ytterbium ion microwave frequency standard
S. Mulholland, H. A. Klein, G. P. Barwood +6
The development of a transportable microwave frequency standard based on the ground-state transition of at ~12.6 GHz requires a compact laser system for coo…
Multimode interferometry for entangling atoms in quantum networks
Thomas D. Barrett, Allison Rubenok, Dustin Stuart +10
We bring together a cavity-enhanced light-matter interface with a multimode interferometer (MMI) integrated onto a photonic chip and demonstrate the potential of such hybrid system…
Measurement of differential polarizabilities at a mid-infrared wavelength in
C F A Baynham, E A Curtis, R M Godun +10
An atom exposed to an electric field will experience Stark shifts of its internal energy levels, proportional to their polarizabilities. In optical frequency metrology, the Stark s…
Absolute frequency measurement of the SF optical clock transition in Yb with an uncertainty of using a frequency link to International Atomic Time
Charles F. A. Baynham, Rachel M. Godun, Jonathan M. Jones +8
The highly forbidden SF electric octupole transition in Yb is a potential candidate for a redefinition of the SI second. We present a…
Frequency comparison of Yb ion optical clocks at PTB and NPL via GPS PPP
J. Leute, N. Huntemann, B. Lipphardt +11
We used Precise Point Positioning, a well-established GPS carrier-phase frequency transfer method to perform a direct remote comparison of two optical frequency standards based on…
