  6. Optical clock - Wikipedia

    en.wikipedia.org/wiki/Optical_clock

    Optical clocks are operated in several experimental systems. For example, many neutral strontium atoms trapped in an optical lattice [1] [4] [5] [6] as well as single aluminum and mercury ions trapped together [7] in an ion trap [8] using the quantum logic technique both form the bases for state-of-the-art optical clocks.
