Which features of quantum physics are not fundamentally quantum but are due to indeterminism?
Flavio Del Santo, N. Gisin
What is fundamentally quantum? We argue that most of the features, problems, and paradoxes – such as the measurement problem, the Wigner's friend paradox and its proposed solutions, single particle nonlocality, and no-cloning – allegedly attributed to quantum physics have a classical analogue if one is to interpret classical physics as fundamentally indeterministic. What really characterizes non-classical effects are incompatible physical quantities, which, in quantum quantum theory are associated to the fundamental constant ℏ .
