# Quantum states may represent the physical reality

#### (To be updated)

This is my term paper for EE547: Quantum Information Processing. The main topic is about Pusey-Barrett-Rudolph (PBR) theorem. In short, the theorem shows that under two classes of assumption (Framework for Ontological Models and Preparation Independence Postulate), the ontological models for quantum theory is $\psi$-ontic, i.e., distinct quantum states represent physical reality, as opposed to the conventional interpretation that quantum states are states of knowledge that only carry parts of information about the reality.

The goal of my work is to review relevant concepts, assumptions, and statement of the PBR theorem in a structured manner. Some criticisms and implications will also be discussed.

I think the topic is philosophically interesting and decide to write a blog post for that. Viewers can take a look at the review in the meantime.
