In recent years ion trap based precision measurement has made tremendous progress in strengthening our understanding of nature. A single or multiple ions in an ion trap after being laser cooled provides the best scenario of perturbation free quantum system. Therefore, it is being applied not only to perform precise quantum state manipulation but also to apply it for probing fundamental symmetries of nature like parity and time reversal. On one hand g-factor measurements on single particle has been performed with exceedingly high precision in Penning traps aiming to compare it with anti-proton, on the other hand ion clocks in Paul traps are becoming more and more precise competing neck-to-neck with optical lattice clocks. On the emerging side ion traps are the simplest devices to test the behaviour of matter close to quantum regime in particular pertaining to thermodynamics and quantum heat engines.
