Abstract
Provided is a method of reducing the magnitude of a quasi-static electric dipole field at the null position of an oscillating electric quadrupole field of an ion trap. The method includes trapping at least one ion in a trapping electric field. The trapping electric field includes an electric field amplitude; using an interferometry sequence including applying a first laser pulse when the trapping electric field amplitude includes a first trapping electric field amplitude; applying a second laser pulse when the trapping electric field amplitude includes a second trapping electric field amplitude different from the first electric field amplitude; and measuring a state of the ion; repeating the interferometry sequence in order to obtain a plurality of measurements of the state of the ion; determining a probability that the trapped ion changes state; and adjusting the trapping electric field based on the determined probability.
