Two-dimensional magnetic insulators exhibit a plethora of competing ground states, such as ordered (anti)ferromagnets, exotic quantum spin liquid states, and random singlet phases. Spin liquids, in particular, are collective phases of matter which have eluded discovery for several decades. Although there are many promising candidate materials for their realization, the central challenges for the clear diagnosis of a spin liquid has been the lack of experimental probes to access their emergent excitations. Here, the authors propose that spin qubit magnetometers grant access to these excitations and, therefore, can be used as a diagnostic of ground states in magnetic insulators.
