  We propose that spin glasses can exist in equally probable superposition
states (SSs) comprising potential configurations. Employing the Edward-Anderson
(EA) order parameter and magnetization, we establish a classification scheme
for these SSs based on their contribution to discerning magnetic order
(disorder), such as SG, ferromagnetic (FM), and paramagnetic (PM) phases. We
also encompass various system sizes and investigate the entanglement properties
of these phase-dependent SSs using the negativity measure. Our analysis reveals
that the SG order parameter can be employed to determine the entanglement
characteristics of magnetically ordered (disordered) phases, and vice versa,
with negativity indicating the presence of magnetic order. Specifically, we
examine the relationship between negativity and susceptibility in spin-glass
systems. Our findings provide further insight into the role of quantum
superposition in spin glasses and quantum magnets.
