The geometric approach to quantum correlations: Computability versus reliability
Tommaso Tufarelli, Tom MacLean, Davide Girolami +2
We propose a modified metric based on the Hilbert-Schmidt norm and adopt it to define a rescaled version of the geometric measure of quantum discord. Such a measure is found not to…
