The goal for this series is simple: to create a university level quantum course and to make it available worldwide, while explaining how quantum information and computation actually works, at a detailed mathematical level. There's no expectation you already know anything about quantum computing or quantum information, or have a background in quantum mechanics or physics. But you will want to be comfortable with linear algebra, complex numbers, and basic mathematical concepts. Understanding Quantum Information and Computation is meant for anyone who wants to learn about quantum computing from a computer scientists perspective, and will begin by covering the basics of quantum information in Unit 1. In unit 2, we will dive into Quantum Algorithms, Unit 3 we'll dive deeper into the mathematics of quantum information, and Unit 4 will explore how to understand and mitigate noise.
