"Quantum Optics 1, Single photons", allowed learners to be introduced to the basic principles of light quantization, and to the standard formalism of Quantum Optics. All the examples were taken in single photons phenomena, including applications to quantum technologies. In the same spirit, "Quantum Optics 2, Two photons and more", will allow learners to use the Quantum Optics formalism to describe entangled photon, a unique feature at the root of the second quantum revolution and its applications to quantum technologies. Learners will also discover how the Quantum Optics formalism allows one to describe classical light, either coherent such as laser light, or incoherent such as thermal radiation. Using a many photons description, it is possible to derive the so-called Standard Quantum Limit (SQL), which applies to classical light, and to understand how new kinds of quantum states of light, such as squeezed states of light, allow one to beat the SQL, one of the achievements of quantum metrology. Several examples of Quantum Technologies based on entangled photons will be presented, firstly in quantum communication, in particular Quantum Teleportation and Quantum Cryptography. Quantum Computing and Quantum Simulation will also be presented, including some insights into the recently proposed Noisy Intermediate Scale Quantum (NISQ) computing, which raises a serious hope to demonstrate, in a near future, the actively searched quantum advantage, ie, the possibility to effect calculations exponentially faster than with classical computers.

The course content is excellent as are the video presentations and quiz questions and, above all, the explanations of concepts.

Great course - follows the first course for the first three lessons, then makes a detour into Bell's inequalities / quantum teleportation where I found the formalism more challenging.
CW
Its an awesome course to dive deep into fundamentals of quantum optics
RK
This was a fascinating journey. The material is extremally interesting and Prof Aspectdelivers it in the best manner. Highly recommended.
PK
Good conventional course about optics based on two photon
NK
Very Interesting course on applied Quantum optics. Includes the latest Quantum Technologies
AK
very good course.Please launch Quantum optics 3 course now
JR
This course presents many relevant examples of current applications of quantum optics. Given that you have retained the information from the first course, the second course is very enjoyable.

Both Quantum Optics I and II were fantastic. I will sign up for the next one the moment it comes out! Dr. Aspect is charming and knowledgable - skilled at getting across tough concepts. The class is not easy, but it is not punishing unnecessarily either. I'll admit that it was good to spend time watching videos through a couple of times instead of working on long homeworks like in QO I. I need to understand where the math comes from in my job, but I am not doing it regularly myself, and so I'd be spending a lot of time on something I would forget pretty quickly. But I like that the classes give you plenty of opportunity to do all the work through, but are also accessible if you don't. I am honestly sad to be done with these for now and can't wait for the third one.
This is a very friendly but also deep course to allow systematic learning. Prof. Aspect provides very clear and smooth lecture on the detailed math to equip students with sufficient knowledge and tool to proceed with self-learning beyond the course (such as reading literature on quantum optics) and do related research. Moreover, he conveys the big picture and prospect of quantum optics, stimulating my interests in this research field.
still more mind enriching than QO1 ! Very happy to discover that there will be a third one ; which of course will be expected impatiently these following weeks. Many thanks to Pr Aspect and the whole team for all this.
The course is fantastic and is in the heart of quantum technologies as the lecturer mentioned. The lectures structure is consistent. I think that the only draw back is the homework not being challenging enough. I also see that the infinite number of attempting the problems is an obstacle to careful thinking before submitting. Overall, I recommend this course to any one desiring to understand quantum optics and related fields. Simply, this is a great course to begin with.
I like the courses (Quantum Optics 1 and 2). There are many concept and application of quantum optics that is very good for someone want to work in quantum science and technology. Beside the course sections, you will learn from a teacher that is one of the best quantum optics leader in world, as you can see his Nobel prize! He knows how to teach complicate concept in simple way at each step. I recomend the course, it helps you to extend your knowledge in quantum optics frontier. I wish all the best for Prof. Aspect and his team.
A very insightful course that looks into the fundamentals, evolution and future of Quantum Optics. Very interesting topics on Quantum Key Cryptography, Quantum repeaters, Quantum teleportation. The most exciting part is the Programmable Quantum Computing and how Quatum Optics is at the very heart of modern Quantum revolution. Thanks to the Professors and Coursera for this wonderful and exciting course. !!!
amazing teaching with a lot of motivation to work in this field. The suggested reading material and papers are very helpful! This course definitely evokes the scientist in the student. Loved it. Look forward to more such courses from the respected professors.
Quantum Optics plays a key role in understanding the matter-light interaction and also various quantum phenomena. I learned many key concepts from this course. I am very thankful to Coursera for this course.
This course presents many relevant examples of current applications of quantum optics. Given that you have retained the information from the first course, the second course is very enjoyable.

This course gives me many concepts and tools which are very important for my research. Thank you! Mr. Aspect and Mr. Brune.
Great course. I did my undergraduated thesis at nonlinear optics and I wanted to prfundize it into quantum optics.
A much expected follow up on the quantum optics I course by Alain Aspect and his gorgeous mustache!
Very Interesting course on applied Quantum optics. Includes the latest Quantum Technologies
Mr Aspect is able to communictae his enthusiasm for the subject. Looking forward to part 3.
I am waiting quantum optics 3: matter-light interactions. When can I see the new course?
Its an awesome course to dive deep into fundamentals of quantum optics
