Abstract
We show that three real-valued parameters govern the quantum motion of an ion stored in the Paul trap. These parameters are two angles of ro tation in phase space and a squeezing parameter. The time dependence o f these parameters simplifies considerably using Floquet solutions. Th is allows us to use the method of quantum state endoscopy to measure a pure state of the vibratory motion of an ion taking into account the full time dependence of the trapping potential.
