majorization and quantum entanglement
... Despite its indisputable usefulness, one might well ask at the outset why we need the notion of majorization when measures of disorder such as the Shannon and von Neumann entropies are already available. Could not these other measures be as useful as majorization? This is a good question. It turns o ...
