TLDR
An optical frequency standard based on the E3 transition of a single trapped (171)Yb+ ion is experimentally investigated and a Ramsey-type excitation scheme that provides immunity to probe-induced frequency shifts is utilized.Abstract:
A twentyfold improvement in the accuracy of a single ytterbium ion atomic clock is achieved using the ion's electric octupole transition.read more

Quantum sensing
Abstract: "Quantum sensing" describes the use of a quantum system, quantum properties or quantum phenomena to perform a measurement of a physical quantity Historical examples of quantum sensors include magnetometers based on superconducting quantum interference devices and atomic vapors, or atomic clocks More recently, quantum sensing has become a distinct and rapidly growing branch of research within the area of quantum science and technology, with the most common platforms being spin qubits, trapped ions and flux qubits The field is expected to provide new opportunities - especially with regard to high sensitivity and precision - in applied physics and other areas of science In this review, we provide an introduction to the basic principles, methods and concepts of quantum sensing from the viewpoint of the interested experimentalist

TL;DR: Local optical clock measurements that surpass the current ability to account for the gravitational distortion of space-time across the surface of Earth are demonstrated and improved techniques allow the measurement of a frequency difference with an uncertainty of the order of 10–19 between two independent optical lattice clocks, suggesting that they may be able to improve state-of-the-art geodetic techniques.
