I'm currently studying ion trap experiments, many papers suggest the cooling of trapped ions, and other papers say its a heating process. I know there's a difference as to what each refers but am unclear of the difference. I'll quote:

Please could someone shed some light on how heating and cooling differ in this statement? What is heated, what is cooled? do both occur at the same time?
Thanks for any ideas.
The interaction of fluctuating electric fields with the motional state of the ion leads to heating and thus to decoherence for entanglement generation limiting the fidelity of quantum logic gates. Effective ground state cooling of trapped ion motion and suppression of motional heating are thus crucial to many applications of trapped ions in quantum information science.
