Particle Tracking Using a Quantum Enhanced Tracker

The quantum enhanced tracker is a proposed tabletop prototype to optically trace single particle paths with high resolution in three dimensions. The electrons pass through a volume filled with Rubidium atoms, and their presence perturbs atomic quantum states and can be detected optically. Here, we show preliminary detection of low-energy electrons in two dimensions through a polarization rotation scheme. We plan to measure AC electric field effects on Rydberg states as a sensitive electrometer to detect low-energy particles. This apparatus will be implemented at Jefferson National Laboratory as a pristine method of detecting charged particles based on coherent properties of Rubidium atoms.
