Four questions for quantum-classical hybrid theory    [PDF]

Hans-Thomas Elze

Four questions are discussed which may be addressed to any proposal of a
quantum-classical hybrid theory which concerns the direct coupling of classical
and quantum mechanical degrees of freedom. In particular, we consider the
formulation of hybrid dynamics presented recently in Ref.[1]. This linear
theory differs from the nonlinear ensemble theory of Hall and Reginatto, but
shares with it to fulfil all consistency requirements discussed in the
literature, while earlier attempts failed. - Here, we additionally ask: Does
the theory allow for superposition, separable, and entangled states originating
in the quantum mechanical sector? Does it allow for "Free Will", as introduced,
in this context, by Diosi [2]. Is it local? Does it provide hints for the
emergence of quantum mechanics from dynamics beneath?
