| Abstract: | We propose a new scheme to estimate the heating rate of trapped ions inthermal states. By applying a controlled-U gate between the internal and themotional states of one of the trapped ions, we could obtain the mean phononnumber from the population of the internal state of the ion. The imperfection due to fluctuations of the relevant parameters in real experiments is considered and we analyze the experimental feasibility of our scheme with sophisticated ion trap techniques. |
