Question

b. The two key assumptions of the EPR argument are locality and realism. Which of these assumptions (may be one or both) is rejected in each of the following popular interpretations of quantum mechanics, and what do each of them say instead? You may find http: //quantumphysics.iop.org/#!article/interpretations-of-quantum-mechanics to be a good place to start reading. i. Copenhagen interpretation. ii. Bohmian mechanics (also known as de Broglie-Bohm pilot wave theory). iii. Everett's many-worlds interpretation.

Explanation / Answer

1).Locality.Existence of all the possible states and collapsing to one of the state upon measurement is real.

2).Locality

3).Realism. The existence of many occupied states before measurement and collapsed of these states to one of the states is fake, instead both the states exist in different equally real worlds. Such as the case of Schrodinger's cat.
