We present and implement a non-destructive detection scheme for the transition probability readout of an optical lattice clock. The scheme relies on a differential heterodyne measurement of the dispersive properties of lattice-trapped atoms enhanced

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

We present a proposal and a feasibility study for the creation and quantum state tomography of a single polariton state of an atomic ensemble. The collective non-classical and non-Gaussian state of the ensemble is generated by detection of a single f

Comparing the frequency of two distant optical clocks will enable sensitive tests of fundamental physics. Here, the authors compare two strontium optical-lattice clocks 690 kilometres apart to a degree of accuracy that is limited only by the uncertai

In this paper, we present recent experiments conducted with two 87Sr optical lattice clocks operated at LNE-SYRTE. We report on the first calibrations of TAI with optical clocks, a necessary step towards the redefinition of the SI second. Additionall

Optical lattice clocks are at the forefront of frequency metrology. Both the instability and systematic uncertainty of these clocks have been reported to be two orders of magnitude smaller than the best microwave clocks. For this reason, a redefiniti

We will report on the recent developments on two operational Sr optical lattice clocks (OLCs) at LNE-SYRTE. In particular, we will emphasize the progress made towards the realization of an optical frequency standard. We will present a nearly continuo
