By locking the frequency of a highly coherent laser for such a quantum transition, we obtain an optical clock, which currently achieves ultimate relative stability in the 18th order and better. While the most accurate optical clocks with trapped ions (optical ion clocks) are based on individual ions, it is advantageous for the laser frequency locking process to use multiple ions simultaneously. By trapping multiple ions in one electrical trap, a so-called set of ions can be obtained in the Coulomb coupled solid-state, known as the Coulomb crystal. A multi-ion approach can provide a higher signal-to-noise ratio for optical ion clocks with improved stability, but only if all the ions in the crystal are sufficiently cooled and homogeneous electric and magnetic field conditions are provided. In this work, we present an overview of methods and implementation of apparatus for trapping and laser cooling of individual ions and Coulomb crystals, which are necessary for implementing optical ion clocks. The work will also present the current state of signal transmission from optical clocks over the photonic network in Europe.
