Fantastic course. I do not have a quantum optics course at my university this course had immediate benefits to my graduate research in quantum optics.

Very clear and informative. The courses are short respectively and they are very exciting. The quizzes are a very good review to keep you concentrated.

Good points:

Accessible material and rigorous worksheets to practice from.

Bad points:

Too many steps were unclear and many derivations skipped.

The subject matter is very interesting and is introduced gradually from the most simple situations to more complex ones.

However many key results are presented without any proof, coming out of the blue. The expressions for the photodetection signals are not sufficiently related to first principles. This is a bit disappointing. Perhaps they assume the student lacks the kowledge to understand the proofs? This would be a contradiction because the homeworks require a very good knowledge of quantum mechanics and its formalism.

The forum seems completely inactive. My questions remain unanswered.

Fantastic course. The homeworks were very hard, but the professors clearly intend for the student to do as much as is comfortable, since typically only 45% is required to pass and that is doable even just with a decent understanding of the material. Prof. Aspect is fantastic. I learned so much from this class! Including some fundamentals that I had either forgotten or never truly understood in an intuitive way. Signed up immediately for QO II.

This was an awesome course. I recommend it to all who are working with Quantum physics, Quantum mechanics, Quantum Optics, Quantum Computing and Information Science, Quantum Communication

There was a steep learning curve but I'm very happy to have deeper understanding of quantum phenomenons. Alain Aspect has a magnificent mustache.

Challenging for an undergraduate student who's only taken an intro course to QM, but very constructive, learned a lot!!! Great course

Challenging and highly insightful course. It erased many misconceptions I had about Photons. Thanks Prof. A. Aspect and Prof. M Burn

This is a really complete course. It it very detailed. Further, the physical insights are just outstanding. Great course.

It’s been 45 years since I last studied quantum mechanics as an undergraduate majoring in experimental physics. I picked this course to kickstart my quantum II career and I was not disappointed. It’s a great course because you are not “spoon fed”. The videos give you the background and the quizzes then get you to think. I now want to do the multi photon course and more quizzes! Thanks.

This is a truly exceptional course, given by masters in the field. We are most fortunate that Alain Aspect, Michel Brune and colleagues at Ecole Polytecnique have made this course possible. I am very much looking forward to Quantum Optics 2! It is great to see that more graduate level physics courses are coming into being on Coursera.

This is a first rate course given by a master of the subject matter. The presentation style - especially for the equations - are easy to follow. The ideas and concepts are concisely explained. The enthusiasm is infectious. I would recommend it to anyone who wants to know the latest developments in quantum optics. I look forward to part 2!

I have barely known anything about quantum mechanics before, but this course is quite informative and helpful for those even without too much prior knowledge. Further, it would be better to start with the first few lectures in quantum optics 2 and then it would be better to embrace the entire courses of quantum optics 1. Good luck.

I am extremely grateful to Prof. Aspect for making such a beautiful course. The organisation was lovely and it really took care of backing things up with mathematical proofs that made it really enjoyable and a fulfilling experience. I am really looking forward to the follow-up course to gain more expertise in this topic

The style of Alain Aspect is very attractive and easy to understand, I have appreciate his first course so I'm enrolled in the second one. The homeworks are very well directed, meaningful and they are an extensión to learn much more. I was very comfortable in the course, I recommend it extensively. Thanks.

This is a well structured course that progressively introduces the concepts and methods. The homework is important and complements (and extends) the course material well. Take care to seek out the errors/typos (especially in the homework) mentioned in the discussion threads.

Un cours que j'ai mis longtemps à travailler et à étudier (7 semaines) puisque que je ne suis pas du tout familier avec la mécanique quantique, mais un cours qui si vous avez la persévérance, vous fera découvrir un monde improbable.

Vraiment super intéressant et complet !!!

I enjoyed the course and learnt a lot. A thorough review of the field quantization for me. It helped me immensely to review my knowledge. It was very useful for "come back" to the subject after my M.Sc. days. For students, you want to learn do the homework sincerely...

This was a high level of education by prof. Aspect who is very experienced. He has an admirable personality and I think he does this for helping public to have access to good education. I hope he continues to create more of these types of courses.
