The classical-quantum boundary for correlations:<? format?> Discord and related measures
One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

Bell nonlocality, entanglement, and entropic uncertainty in a Heisenberg model under intrinsic decoherence: DM and KSEA interplay effects
Bell's inequalities are described by the sums of correlations including non-commuting
observables in each of two systems. Bell's inequalities violation is possible since the …

From quantum coherence to quantum correlations
In quantum mechanics, quantum coherence of a state relative to a quantum measurement
can be identified with the quantumness that has to be destroyed by the measurement. In …
