Wave particle duality resolved

The mysterious wave particle duality issue of whether quantum mechanical systems behave as a particle or wave seems to have been resolved. 

On a very rough reading the reason a quanta of energy appears in one place and not another seems to be re-interpreted as a maximum versus a minimum of entropy of a system. 

This is noted in the abstract as :

Here we show that WPDRs [wave–particle duality relations] correspond precisely to a modern formulation of the uncertainty principle in terms of entropies, namely, the min- and max-entropies. This observation unifies two fundamental concepts in quantum mechanics.


This comes from the folks at Centre for Quantum Technologies at the National University of Singapore.
