Separability Criteria from Uncertainty Relations
Otfried Guehne, Maciej Lewenstein
abstract: We explain several separability criteria which rely on uncertainty relations.
For the derivation of these criteria uncertainty relations in terms of
variances or entropies can be used. We investigate the strength of the
separability conditions for the case of two qubits and show how they can
improve entanglement witnesses.
