# Exhaustive list of assumptions for the Clauser-Horne-Shimony-Holt inequality

I am trying to create an exhaustive list of all assumptions which work as the base of the CHSH inequality.

1. Locality - this means an object can be influenced only by its surroundings. So, the events taken place at Alice and Bob's ends cannot influence each other.
2. Realism - the value of the observed quantity is independent of observation.
3. The quantity being observed is a discrete random variable.
4. Repeated rounds of experiments are independent of each other and evenly distributed.
5. A measurement will always produce a result (a photon will always be detected).
6. No enhancement assumption - it means when a measuring setup is placed between the source of the entangled particle and a detector the probability of measurement doesn't increase.

Am I missing anything?
