Unconditional no-hidden-variables theorem
نویسنده
چکیده
We present ultimate version of no-hidden-variables theorem. We shall derive a proposition under the existence of the Bloch sphere in a single spin-1/2 system. The existence of a single classical probability space for measurement outcome within the formalism of von Neumann’s projective measurement cannot coexist with the proposition. Namely, we have to give up the existence of such a classical probability space for measurement outcome in the two-dimensional Hilbert space formalism of the quantum theory. Thus, the quantum theory cannot accept any hidden-variable interpretation even in the two-dimensional space.

What is wrong with von Neumann ’ s theorem on ” no hidden variables ”
It is shown that, although correct mathematically, the celebrated 1932 theorem of von Neumann which is often interpreted as proving the impossibility of the existence of " hidden variables " in Quantum Mechanics , is in fact based on an assumption which is physically not reasonable. Apart from that, the alleged conclusion of von Neumann proving the impossibility of the existence of " hidden var...

متن کاملConsistent histories , quantum truth functionals , and hidden variables
A central principle of consistent histories quantum theory, the requirement that quantum descriptions be based upon a single framework (or family), is employed to show that there is no conflict between consistent histories and a no-hidden-variables theorem of Bell, and Kochen and Specker, contrary to a recent claim by Bassi and Ghirardi. The argument makes use of “truth functionals” defined on ...
متن کاملLeggett’s theorem without inequalities
We prove a no-go theorem for a class of hidden variables theories that satisfy parameter independence. Specifically, we show that, assuming two conditions, there are no non-trivial hidden variables models of the quantum predictions for product measurements on two systems in any maximally entangled state in a Hilbert space of dimension at least 3× 3. The two conditions are parameter independence...
متن کاملToy Quantum Mechanics Using Hidden Variables
It is used to state that no local theory assuming any kind of evolving-in-time physical field (hidden variables) can reproduce the same predictions as standard quantum mechanics. Bell formulated a corresponding theorem in [1]. An advanced variant of the theorem was proposed in [2]. Feynman, in [3], stated another but analogous idea: not any classical computational device (even when probabilisti...
