Optical atomic clocks represent the state of the art in the frontier of modern measurement
science. In this article a detailed review on the development of optical atomic clocks that are …

In the last ten years extraordinary results in time and frequency metrology have been
demonstrated. Frequency-stabilization techniques for continuous-wave lasers and …

MAGIS-100 is a next-generation quantum sensor under construction at Fermilab that aims to
explore fundamental physics with atom interferometry over a 100 m baseline. This novel …

We report on an improved systematic evaluation of the JILA SrI optical lattice clock,
achieving a nearly identical uncertainty compared to the previous strontium record set by the …

Optical atomic clocks, due to their unprecedented stability,–and uncertainty,,–, are already
being used to test physical theories, and herald a revision of the International System of …

We experimentally investigate an optical frequency standard based on the S 1/2 2 (F= 0)→ F
7/2 2 (F= 3) electric octupole (E 3) transition of a single trapped Yb+ 171 ion. For the …

The pursuit of better atomic clocks has advanced many research areas, providing better
quantum state control, new insights in quantum science, tighter limits on fundamental …

A list of standard reference frequency values (LoF) of quantum transitions from the
microwave to the optical regime has been recommended by the International Committee for …

Progress in atomic, optical and quantum science, has led to rapid improvements in atomic
clocks. At the same time, atomic clock research has helped to advance the frontiers of …

State-of-the-art laser frequency stabilization by high-finesse optical cavities is limited
fundamentally by thermal noise-induced cavity length fluctuations. We present a novel …
