Course Description

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 b...

Prior Experience in Subject: Undergraduate level "Linear Algebra" course. The course is beautifully designed starting with an Introduction to Quantum Mechanics. In a couple of weeks, we are already applying gates and dealing with circuits as we start dealing with Quantum Computation, yet it does so in a very gradual and gentle manner. Before you know, you are already face to face with Quantum Algorithms, but still it never feels like you are being rushed into a topic. The last few weeks deal with Schrödinger's equation, Quantum Systems and how to practically implement these qubits. I somehow cannot wrap my head around the fact that I learnt so much in like 10 weeks! I can now perform magical things like: Perform tensor products! (Tensor sounded really scary before I took this course) Use the Dirac Bra-Ket Notations for qubits! (Those little angles don't look complex now) Showing you how Quantum Teleportation works! How weird and beau... Prior Experience in Subject: Undergraduate level "Linear Algebra" course. The course is beautifully designed starting with an Introduction to Quantum Mechanics.

How to implement these qubits through Spin! ...and countless more things If you are even slightly curious about this topic, you should definitely give this a try. I really hope there's another advanced course to follow this one up. Thank you so much CS191x team!

This course is an excellent initiative to introduce popular and important subjects - Quantum Mechanics and Quantum Computation to people in an easy to understand way on which they can decide/build their future efforts to know more on the same. I strongly urge - "edX" and Prof. Vazirani to re-launch the course at earliest, for the benefit of so many people who want to benefit from this fabulous course.

Very interesting material. The first time I tried this course I dropped it because I thought it was getting to be above my level but I tried it again and found that with a little review of linear algebra it was quite manageable. It does not require any background in quantum mechanics and in fact serves nicely as a first exposure to that field. My only criticism of the course was that the final lectures got a little esoteric and the tone got a bit contentious as the professor took apart claims than an actual quantum computer has been built.

This course is an excellent introduction to Quantum Computation and a revision of Quantum Mechanics concepts with such an educational twist, that it will even surprise a formal physicist. It makes you think deep about how to exploit QM facts to actually compute things. Prof. Vazirani's presentations are clear, inspiring and engaging. This is an enjoyable course and I highly recommend it.

An introductory course to anyone interested in learning more about the emerging field of quantum computation. Quantum mechanics required to understand the subject will be taught in the course. A knowledge of linear algebra (and perhaps basic calculus) will be helpful. I am a physics major and have worked quite a bit in this area before doing the course. But I liked the way Prof. Vazirani approached the topic. When I took the course, it ended at Quantum search and complexity theory. I wish a bit of Quantum Information is also covered in future editions of the course.

This was a really awesome course. I purchased book on quantum computing in 1997 but I never really focused on its content. This is my first EDX course. The math was fairly easy except the summation over {0,1} and the modular arithmetic. This took me sometime to figure out. I thought it was real cute how the course exposed the DWAVE marketing .hoax. I would recommend this course.

This was my first formal exposure to quantum mechanics and quantum computation. I think this course provides an excellent introduction to these topics. The video lectures are clear and concise. The topics covered give a broad overview of a range of topic in this area. The homework and exams are challenging but rewarding. I found the written notes very helpful in reviewing the material after the class. A more detailed discussion of status & challenges of practical implementation of quantum computing would make the course even more interesting for me. Overall an excellent course, I recommend it to others wanting to learn more about this area.

Always been interested in Quantum mechanics used in Information Technology but could not quite learn it because there were no one with significant knowledge in this topic around me. But this couse is a complete satisfaction to me as it provided such complex technological implementations so simply.

This is a great course if you're looking for a reasonably deep introduction to the topic, but don't have the maths background usually assumed by such courses (a diagnostic quiz is available at the start of the course to give you some idea of where you stand on this front, and what kind of prior knowledge will be assumed). I come from a CS background, and found that the course's approach, focusing more on computation than physics in the early weeks, was very helpful in easing me into the later material. I've attempted other online QM courses in the past, but have always dropped out in the first couple of weeks due to an insufficient maths background; having completed this one, I feel much better prepared to go back and reattempt the others.

This course was very cool!!! I loved it very much and I suggest this to any one who wants to explore many secrets of this universe and the abstruse thought subject of Quantum Mechanics. The professor Vazirani explained the difficult seeming subject with ease and it was a great experience overall. I will not disclose the topics you will learn in this course because I want it to be a completely new experience, But I assure you that you will cherish this course for a long time. Welcome to the amazing world of Quantum Mechanics!!!

I am not a physics major. I am a retired electrical engineer with a post- graduate degrees. I basically was a course auditor. I wanted to learn the material while I did not want to be encumbered with the doing the assignments and dealing with the pressure of schedules. I watched all the lectures, and really enjoyed them. The prof made an excellent presentation of all the material. Actually he made a very complex subject seem simple. I learned a lot, and he cleared up many things for me. I would highly recommend this course to anyone interested in this material as the prof presented the material in a very nice way.

I'm a PhD student working on this topic but not understand many things. Little bit aware about this subject. This course help me lot and I'll wait for another course following this one which help us in research purpose. It would be very much helpful to us if some problem was discussed or given as for example in the materials. Thankful to Prof. Umesh Vazirani all the TA of edx group to provide us such courses.

Great class. Very informative. For those of use out of school for a while, it provides a pretest to assess which skills needs to be refreshed before commencing the class. It also provides links to resources so you can refresh your skills without having to spend time trying to find where you can do that online.

Prior Experience : I don't have prior experience with the quantum computation but I have experience with classical computation. That helped me. This course was very interesting to me. Compare to others: I like this course very much because quantum computation is the new way of computing that will drive the age of information. I am very proud to complete this course with good understanding of basics. Likes : Way of teaching and explanation was super. Framing syllabus and questions are very great. Alice and Bob questions are very interesting to solve real world problems. Dislike : Quantum algorithms, factorial algorithms were taught little bit faster and less explained. For next time elaborate them more and allocate one or two weeks more to those parts.
