  Characterization and categorization of quantum correlations are both
fundamentally and practically important in quantum information science.
Although quantum correlations such as non-separability, steerability, and
non-locality can be characterized by different theoretical models in different
scenarios with either known (trusted) or unknown (untrusted) knowledge of the
associated systems, such characterization sometimes lacks unambiguous to
experimentalist. In this work, we propose the physical interpretation of
nonlocal quantum correlation between two systems. In the absence of {\it
complete local description} of one of the subsystems quantified by the {\it
local uncertainty relation}, the correlation between subsystems becomes
nonlocal. Remarkably, different nonlocal quantum correlations can be
discriminated from a single uncertainty relation derived under local hidden
state (LHS)-LHS model only. We experimentally characterize the two-qubit Werner
state in different scenarios.
