We search for transient variations of the fine structure constant using data from a European network of fiber-linked optical atomic clocks. By searching for coherent variations in the recorded clock frequency comparisons across the network, we signif

In this paper we report the evaluation of an optical lattice clock based on neutral mercury with a relative uncertainty of $1.7\times {10}^{-16}$ . Comparing this characterized frequency standard to a ^133 Cs atomic fountain we determine the absolute

The second quantum revolution is underway and the deployment of Quantum Technologies (QT) keeps pace with it. This technological paradigm-switch creates opportunities and challenges for industry, innovation and society. Several large companies, as we

We demonstrate a method for accurately locking the frequency of a continuous-wave laser to an optical frequency comb in conditions where the signal-to-noise ratio is low, too low to accommodate other methods. Our method is typically orders of magnitu

We report on the recent improvements of the mercury optical lattice clock based on 199Hg operating at LNESYRTE. In particular we describe how the exploitation of a 2D Magneto Optical Trap (2D-MOT) allowed us to increase significantly the number of us

Some 50~years ago, physicists, and after them the entire world, started to found their time reference on atomic properties instead of motions of the Earth that have been in use since the origin. Far from being an arrival point, this decision marked t
