Do degrees of entanglement just measure different kinds of correlations or different kinds of entangled states.
I presume that maximally entangled state are more likely to engender deterministic correlations (or have pairs of measurement values which engender strict anti-correlation or perfect correlation) and thus ingender greater violations of bells inequality;
(1)but do these degrees of entanglement correspond to totally different states; some kind of partially coherent singlet state,which can be measured along all bases; or do they just correspond to the particular (or sets of bases, given that we are talking about two or more particles that are entangled) in which one entangled state can be measured, where the different bases of the multiple particle engender different correlations and thus different violations or more or less inequalites, to more or less degrees
(2)or is there only one kind of entanglement, and where the degree of entanglement just measures the kind of correlations (probabilistic, how probabilistic, deterministic) indirectly by determining by what degree each such kind of correlation or sets of correlations violate bell inequality. I presume the former, which somehow corresponds roughly (inversely) to the degree of dechorence
For example is a singlet state just
(1) a maximally entangled state simplicter, so that partial entanglement or mere degrees of entangled pertain to different states entirely which have somewhat de-cohered.
(2)Does the maximal entanglement only correspond to when it is measured along these directions spin y in both directions of two particles prepared in x in a singlet state, which induce perfect anti correlation or perfect correlation?
