In order to perform the readout of the qubit state, it is imperative to detect the Rydberg state of an individual SE. For this purpose, we employ a high Q-factor LC resonator for RF reflectometry, a technique previously established for electrons in semiconductors [2]. We experimentally validated the feasibility of this approach with an ensemble of many SEs and are now advancing our efforts to implement this technique for a single SE.
