In particular, there are (infinitely many) quantum states ρ for which the function Wρs is not a regular probability distribution for some values of s, as it can assume negative values or even be singular in certain points of the phase space. An exception is the case s = −1, which corre ...

A Combinatorial Approach to Nonlocality and Contextuality
... quantum theory is at variance with any attempt at assigning deterministic values to all observables in a way which would be consistent with the functional relationships between these observables predicted by quantum theory. This impossibility is generally known as contextuality, since it means that ...

Limits on Efficient Computation in the Physical World
... More than a speculative technology, quantum computing seems to challenge our most basic intuitions about how the physical world should behave. In this thesis I show that, while some intuitions from classical computer science must be jettisoned in the light of modern physics, many others emerge nearl ...
