Quantum logic spectroscopy uses the quantized motion of trapped charged particles as a means to indirectly control charged quantum systems and gain information on their properties. A highly controllable atomic "logic" ion indirectly helps to manipulate the system under study and to report information back to the experimenter. This allows for precise quantum control of charged systems that are hard or impossible to directly control with light fields, such as atomic ions without convenient laser cooling transitions, molecular ions or charged elementary particles such as the proton. This talk will introduce the basic ideas behind quantum logic spectroscopy and illustrate its power based on example experiments in the NIST Ion Storage Group.
