## Entanglement Entropy: Quantum Field Theory

Part 1: Quantum Mechanics [This article expects the reader to have some experience with quantum field theory and path integrals] [I should also make a disclaimer here, some parts of this article uses some results from conformal field theory which is beyond my knowledge. So I have to just state the results in those parts….

Particle physics master’s student at the university of Tehran, Tehran, Iran.

I’m working on my master’s thesis which is a review of the Ryu-Takayanagi prescription to calculate the entanglement entropy of a CFT using AdS/CFT correspondence.
