No Fine Theorem for Macrorealism: Limitations of the Leggett-Garg Inequality
No Fine Theorem for Macrorealism: Limitations of the Leggett-Garg Inequality
Tests of local realism and macrorealism have historically been discussed in very similar terms: Leggett-Garg inequalities follow Bell inequalities as necessary conditions for classical behavior. Here, we compare the probability polytopes spanned by all measurable probability distributions for both scenarios and show that their structure differs strongly between spatially and …
