Bell’s Theorem, Amplitudes, and Trigonometry, 2 pages.

Abstract

Bell’s theorem adds probabilities when it should use amplitudes. With amplitudes and trigonometric identities, a theory in which the result at one detector does not depend on the other detector’s setting or outcome can produce the correct statistics for a Bell test. When a photon’s polarization before a measurement is a hidden variable, Bell’s theorem thus does not rule out local realism.

Notes

I’ve previously written about Bell tests and local realism.
