Operation of a Cryogenic Paul Trap for Electrons

POSTER

Abstract

We report our recent experimental progress on the operation of a microwave Paul trap for electrons in a cryogenic environment. Cryogenic operation is an essential step towards quantum information processing on this platform, which offers potential for faster gate operations than trapped-ion systems and can be free from internal state leakage due to the electron's low mass and simple structure. We characterized the electron trapping behavior in a few-Kelvin environment using the same trap design previously demonstrated at room temperature and developed a cryogenic-compatible continuous-wave laser-heated oven for loading electrons. These results identify evidence consistent with persistent surface charging as a limiting factor and point the way towards scaling trapped electron platforms to cryogenic quantum experiments by informing improvements involving materials, shielding, and optics.
