The Bell Inequality tests are only valid for positive numbers, which is reasonable because counts and probabilities cannot be negative. CHSH generates a negative number, which means CHSH experiments are invalid.(adsbygoogle = window.adsbygoogle || []).push({});

Bell's Inequality can be violated by having a negative value.

For example:

P(a,b) -P(a,d)+P(c,b)+P(c,d) <= 2

Which can be calculated as

a+b-a-d+c+b+c+d / a+b+c+d <=2

with

a=1, b=2, c=3 and d= - 4

then

1+2-1-(-4)+3+2+3+(-4) / 1+2+3+(-4) <= 2

10 /2 <= 2

5 <= 2

Is this correct?
