Conformal field theories are magical

Abstract: Stabilizer states are an important subclass of quantum states that play an important role in quantum error correction, topological order, and toy models of holography, among many other applications. It is also important to quantify the extent to which a given state lies beyond the stabilizer set, a resource known as magic. I will discuss the concept of magic and some of its measures in many-body physics, focusing on a particular 1d spin chain which flows to a conformal field theory in the infrared. Based on a work to appear with Christopher White and Charles Cao.
