Entanglement & MWI of Quantum Mechanics

Abstract

According to Many Worlds Interpretation ("MWI", Everett, 1957), the terms of an entangled state describe something that really exist; the state does not just refer to the probabilities of results that would be obtained if measurement takes place. We argue in this essay from conceptual point of view the relationship between quantum entanglement and and MWI. The debate is still open and we suggest that the objective Bayesian interpretation of quantum probability could be an interesting approach to solve this fundamental question.
