Monogamy - Why Alice and Bob don't get out enough

In scenarios such as cryptography, Alice and Bob, the ubiquitous players of quantum games, derive special benefits from the monogamous relationship of quantum correlations. In this talk, I will argue that it is also at the root of why the macroscopic world of our daily experience does not require a description based on probability amplitudes i.e. how local realism emerges out of quantum mechanics, which is fundamentally not local realistic. If time permits, I will also illustrate the relation between the monogamy of quantum correlations and the ability to clone an unknown quantum state.
