In this talk, we're going to multiply low-dimensional matrices over $\mathbb C$! It'll be just like Ma1b, except way cooler because we'll use bras and kets. We'll introduce the notion of entanglement and show how using just little bit of it turns a classical phone lines into quantum teleporter. We'll also provide a winning quantum strategy for a classically impossible game. Hopefully, you'll leave this talk with an appreciation for the fact that quantum'' is the best adjective in all of math, physics, and computer science.
