@Guy vandegrift: Waiting for comment

## Student poster[edit source]

We need a student poster explaining how students can use primitive geometry (Euclidean without the proofs or constructions) to derive the factor of 1/2 in the electric field output. Basically its just a 30-60 right triangle.

The hard part is displaying how the remote photon is used to deduce the local photon's polarization along some axis before the local photon is measured.

A basic tenant of QM is that measurements change the state of an object. A good example is scrhodingers cat.--Guy vandegrift (discuss • contribs) 16:48, 5 October 2015 (UTC)
