Progress on the optical lattice clock
Comptes Rendus. Physique, Volume 16 (2015) no. 5, pp. 499-505.

Optical lattice clocks have made significant leaps forward in recent years, demonstrating the ability to measure time/frequency at unprecedented levels. Here we highlight this progress, with a particular focus on research efforts at NIST and JILA. We discuss advances in frequency instability and the characterization of key systematic effects, with a brief outlook to the future.

Les horloges optiques en réseau ont fait des progrès significatifs ces dernières années, en démontrant la possibilité de mesurer le temps et les fréquences à un niveau jamais atteint auparavant. Dans cet article, nous illustrons ces progrès en nous focalisant sur les efforts de recherches au NIST et au JILA. Nous discutons les avancées au niveau de l'instabilité de fréquence et de la caractérisation des effets systématiques clés, et nous donnons un bref aperçu des perspectives futures.
