Quantum Information and Computing

This lecture introduces the fundamentals of quantum information and computing, covering topics such as quantum mechanics, digital quantum computing, universal quantum gates, quantum algorithms (Deutsch, Deutsch-Jozsa, Schor's factoring, Grover's search), open quantum systems, quantum error correction, and hybrid quantum algorithms. The course also discusses Google's quantum supremacy announcement in 2019 and the skills needed to understand it. Additionally, it explores the notion of classical and quantum computational complexity, errors in quantum computation, and quantum circuits. The lecture delves into the concept of quantum information and the challenges in quantum computing, providing an outlook on the field.
