Proposed Test of Relative Phase as Hidden Variable in Quantum Mechanics
We consider the possibility that the relative phase in quantum mechanics plays a role in determining measurement outcome and could therefore serve as a “hidden” variable. The Born rule for measurement equates the probability for a given outcome with the absolute square of the coefficient of the basis state, which by design removes the relative phase from the formulation. The value of this phase...
متن کاملOn the Status of Hidden Variable Theories in Quantum Mechanics
1. Quantum theory vs. hidden variables It takes time for new paradigms to be generally digested and become known. It also takes time to change some of the old paradigms once they have been used for some time. So one has become accustomed to the conclusion , although deeply disturbing, that no hidden variable models can be introduced into quantum theory, i.e., there is a limit to our knowledge. ...
متن کاملUse of a Canonical Hidden-Variable Space in Quantum Mechanics
In Brandenburger and Keisler (2012b) we showed that, provided only that the measurement and outcome spaces in an experimental system are measure-theoretically separable, then there is a canonical hidden-variable space, namely the unit interval equipped with Lebesgue measure. Here, we use this result to establish a general relationship between two kinds of conditions on correlations in quantum s...
متن کاملContradiction of Quantum Mechanics with Local Hidden Variables for Continuous Variable Quadrature Phase Amplitude Measurements
We demonstrate a contradiction of quantum mechanics with local hidden variable theories for continuous variable quadrature phase amplitude (“position” and “momentum”) measurements, by way of a violation of a Bell inequality. For any quantum state, this contradiction is lost for situations where the quadrature phase amplitude results are always macroscopically distinct. We show that for optical ...
متن کاملNonlocal Hidden-Variable Theories and Quantum Mechanics: An Incompatibility Theorem
It is argued that among possible nonlocal hidden-variable theories a particular class (called here ‘‘crypto-nonlocal’’ or CN) is relatively plausible on physical grounds. CN theories have the property that (for example) the two photons emitted in an atomic cascade process are indistinguishable in their individual statistical properties from photons emitted singly, and that in the latter case th...
