    "abstract": "In this work a family of quantum nondemolition variables for the case of a\nparticle caught in a Paul trap is obtained. Afterwards, in the context of the\nso called restricted path integral formalism, a continuous measuring process\nfor this family of parameters is considered, and then the corresponding\npropagators are calculated. In other words, the time evolution of a particle in\na Paul trap, when the corresponding quantum nondemolition parameter is being\ncontinuously monitored, is deduced. The probabilities associated with the\npossible measurement outputs are also obtained, and in this way new theoretical\nresults emerge, which could allow us to confront the predictions of this\nrestricted path integral formalism with the readouts of some future\nexperiments.",
