Hidden Variables and Commutativity in Quantum Mechanics
نویسنده
چکیده
This paper takes up a suggestion that the reason we cannot find hidden variable theories for quantum mechanics, as in Bell’s Theorem, is that we require them to assign joint probability distributions on incompatible observables; these joint distributions are empirically meaningless on one standard interpretation of quantum mechanics. Some have proposed to get around this problem by using generalized probability spaces. I present a “no-go” theorem to show a sense in which generalized probability spaces can’t serve as hidden variable theories for quantum mechanics, so the proposal for getting around Bell’s Theorem fails.

Can hidden variables theories meet quantum computation?
We study the relation between hidden variables theories and quantum computation. We discuss an inconsistency between a hidden variables theory and controllability of quantum computation. To derive the inconsistency, we use the maximum value of the square of an expected value. We propose a solution of the problem by using new hidden variables theory. Also we discuss an inconsistency between hidd...
متن کاملCompatibility and probability
The notion of “incompatibility” of system variables arose with quantum mechanics; it is inconceivable in classical physics. Two expressions of incompatibility from the earliest days of quantum theory are the uncertainty principle of Heisenberg (measurement of one variable causes uncontrollable disturbance in other variables) and Bohr’s “complementarity” (not all variables have simultaneous “rea...
متن کاملClassical Probability and Quantum Outcomes
There is a contact problem between classical probability and quantum outcomes. Thus, a standard result from classical probability on the existence of joint distributions ultimately implies that all quantum observables must commute. An essential task here is a closer identification of this conflict based on deriving commutativity from the weakest possible assumptions, and showing that stronger a...
متن کاملOutlier Detection Using Extreme Learning Machines Based on Quantum Fuzzy C-Means
One of the most important concerns of a data miner is always to have accurate and error-free data. Data that does not contain human errors and whose records are full and contain correct data. In this paper, a new learning model based on an extreme learning machine neural network is proposed for outlier detection. The function of neural networks depends on various parameters such as the structur...
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...
