Abstract

A highly sensitive electrometer is reported that is based on a Schrödinger-cat state in a Rydberg atom, that reaches a sensitivity beyond the standard quantum limit and can compete with state-of-the-art electric field measurements performed using electromechanical resonators and single-electron transistors.
