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 by a

Demonstration of the Systematic Evaluation of an Optical Lattice Clock Using the Drift-Insensitive Self-Comparison Method [PDF]
The self-comparison method is a powerful tool in the uncertainty evaluation of optical lattice clocks, but any drifts will cause a frequency offset between the two compared clock loops and thus lead to incorrect measurement result.

Construction of optical system for an atomic clock-beyond atomic fountain
We demonstrate the construction of the optical system in the atomic clock-beyond atomic fountain based on 87Rb atom. The optical system includes a high-stability laser system and an optical lattice.

Toward a quantum-enhanced strontium optical lattice clock at INRIM [PDF]
The new strontium atomic clock at INRIM seeks to establish a new frontier in quantum measurement by joining state-of-the-art optical lattice clocks and the quantized electromagnetic field provided by a cavity QED setup.

The Zeeman shift plays an important role in the evaluation of optical lattice clocks since a strong bias magnetic field is applied for departing Zeeman sublevels and defining a quantization axis.

Experimental determination of the E2-M1 polarizability of the strontium clock transition
To operate an optical lattice clock at a fractional uncertainty below 10^{−17}, one must typically consider not only electric-dipole (E1) interaction between an atom and the lattice light field when characterizing the resulting lattice light shift of the

Recent Advances Concerning the 87Sr Optical Lattice Clock at the National Time Service Center
We review recent experimental progress concerning the 87Sr optical lattice clock at the National Time Service Center in China. Hertz-level spectroscopy of the 87Sr clock transition for the optical lattice clock was performed, and closed-loop operation of

Blackbody radiation shift in strontium lattice clocks revisited
We reevaluate the blackbody radiation (BBR) induced ac-Stark shift of the strontium clock transition (5s5p)^{3}P_{0}-(5s^{2})^{1}S_{0} at 698nm used as reference in optical lattice clocks and as secondary representation of the SI unit “second.” At room ...

Improving the Q Factor of an Optical Atomic Clock Using Quantum Nondemolition Measurement
Quantum nondemolition (QND) measurement is a remarkable tool for the manipulation of quantum systems. It allows specific information to be extracted while still preserving fragile quantum observables of the system.
