We demonstrate experimentally a protocol for superresolution quantum sensing that resolves two incoherent signals with sub-kHz frequency separation using a solid-state spin sensor. By utilizing the naturally occurring signal noise, we identify optimal interrogation times to make the estimation uncertainty remains finite even when the signal frequencies approach each other.
