【Abstract】
A new measurement underway in completely new apparatus seeks to greatly improve upon the 1 part in 10^{13} measurement of the electron magnetic moment that our research group announced in 2023. The motivation for making the most precise measurement ever made of a property of an elementary particle is to test the most precise prediction of the Standard Model of particle physics. A one-electron, relativistic, quantum cyclotron is realized to enable these measurements. Essential quantum methods include quantum non-demotion detection (QND), quantum jump spectroscopy, cavity-inhibited spontaneous emission, and quantum-limited detectors. The importance of a new measurement of the fine structure constant will be discussed as well.
