A simple conceptual introduction to quantum mechanics and quantum computation.

Quantum computation is a remarkable subject building on the great computational discovery that computers based on quantum mechanics are exponentially powerful. This course aims to make this cutting-edge material broadly accessible to undergraduate students, including computer science majors who do not have any prior exposure to quantum mechanics. The course starts with a simple introduction to the fundamental principles of quantum mechanics using the concepts of qubits (or quantum bits) and quantum gates. This treatment emphasizes the paradoxical nature of the subject, including entanglement, non-local correlations, the no-cloning theorem and quantum teleportation. The course covers the fundamentals of quantum algorithms, including the quantum fourier transform, period finding, Shor's quantum algorithm for factoring integers, as well as the prospects for quantum algorithms for NP-complete problems. It also discusses the basic ideas behind the experimental realization of quantum computers, including the recent Google quantum supremacy experiment. Before your course starts, try the new edX Demo where you can explore the fun, interactive learning environment and virtual labs. Learn more.

**Do I need a textbook for this class?**

No. Notes will be posted each week. If you wish to consult other references, a list of related textbooks and online resources will be provided.

**What is the estimated effort for course?**

About 5-12 hrs/week.

**Why is the work load range so wide?**

How long you spend on the course depends upon your background and on the depth to which you wish to understand the material. The topics in this course are quite open ended, and will be presented so you can understand them at a high level or can try to follow it at a sophisticated level with the help of the posted notes.

**How much does it cost to take the course?**

Nothing! The course is free.

**Will the text of the lectures be available?**

Yes. All of our lectures will have transcripts synced to the videos.

**Do I need to watch the lectures live?**

No. You can watch the lectures at your leisure.
