1. In Bell's famous (1964), at eq. 3, we see the QM formulation for the EPRB expectation:
P(a,b) = <σ1.a σ2.b> = -a.b. (1)
2. I have no issue with this QM formulation BUT: There are surprisingly many QM ways to achieve the result.
3. So I am SERIOUSLY interested in collecting all such QM ways: especially the shortest AND your favourite AND those using Dirac notation!
4. I will happily share all that I find. PM me if you'd like a direct email connection for attachments, etc; privacy assured!
