Yes, there could be“hidden variables.”.
(2) There are hidden variables, so the results of the experiments are pre-ordained; or.
Bell thus supported realism in the form of hidden variables.
But sometimes those hidden variables really aren't important.
There might be other quantities giving extra information-- hidden variables.
Her field of study was known as“Hidden Variables and Non-locality in Quantum Theory”.
It was not the objective measurable predictions of quantum mechanics which ruled out hidden variables.
The other property of hidden variables that Bell demonstrated was that they must be contextual.
Thus"it is not the objective measurable predictions of quantum mechanics which rules out local hidden variables.
Non-locality and hidden variables are two proposed mechanisms that enable the effects of entanglement.
Nevertheless it would appear natural that the possibility of supplementing the Schrödinger equation with hidden variables would have been taken seriously.
No physical theory of local hidden variables can ever reproduce all of the predictions of quantum mechanics.
The probability statements made by quantum mechanics are irreducible in the sense that they don't just reflect our limited knowledge of some hidden variables.
Once this mistake was realised,it was clear that hidden variables theories of quantum theory were possible.
Thus hidden variables cannot be thought of as saying what value a quantity'has', only what value we will get if we measure it.
There is no physical theory for local hidden variables which can reproduce the quantum mechanics predictions.
They were therefore pleased when John von Neumann proved a theorem claiming to show rigorously that it is impossible to add hidden variables to the structure of quantum theory.
Bell thought that no physical theory of local hidden variables can ever reproduce all of the predictions of quantum mechanics.
(The expectation value of a variable is the mean of the possible experimental results weighted by their probability of occurrence.) Once this mistake was realised,it was clear that hidden variables theories of quantum theory were possible.
In EPR-type experiments,this inequality is obeyed by local hidden variables, but may be violated by other theories, including quantum theory.
A complete theory of hidden variables must actually be more complicated than this-- we must remember that we wish to predict the results of measuring not just sz, but also sx and sy, and any other component of s.
He was delighted by the creation in 1952 by David Bohm of a version of quantum theory which included hidden variables, seemingly in defiance of von Neumann 's result.
He found that, even when hidden variables are allowed, in some cases the result obtained in one wing must depend on which component of spin is measured in the other; this violates locality.
And although most physicists now accept the strangelaws of quantum mechanics, the new experiment makes it even harder to claim that hidden variables- those yet to be dreamed up by scientists- explain particles' strange behavior.
Von Neumann had illegitimately extended to his putative hidden variables a result from the variables of quantum theory that the expectation value of A+ B is equal to the sum of the expectation values of A and of B.
The opening of the counterintuitive principles of quantum mechanics in the 20s of the last century led many physicists, including albert Einstein,to suspect that their unusual work is explained by some unknown principles and hidden variables, which can be described by the language of classical physics.
But in 1964, Irish physicist John Stewart Bell proposed a mathematical way to check whether hidden variables or weird non-locality(the idea that entangled particles can communicate faster than the speed of light) explained the behaviors.
And there are,as shown by Bell, no hidden variables(information about the system hidden to us) that could tell us where it will be pointing if we just had more information(this is what I mean when I say that we know everything we could possibly know about the spin).
