The Significance of Measurement Independence for Bell Inequalities and Locality
[chapter]
2016
Fundamental Theories of Physics
A local and deterministic model of quantum correlations is always possible, as shown explicitly by Brans in 1988: one simply needs the physical systems being measured to have a suitable statistical correlation with the physical systems performing the measurement, via some common cause. Hence, to derive no-go results such as Bell inequalities, an assumption of measurement independence is crucial. It is a surprisingly strong assumption -less than 1/15 bits of prior correlation suffice for a local
