"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....

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.

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.

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.

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. !!!

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.

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.

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

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.

The course is a series of excellent lectures, covering fascinating topics. It follows on from the earlier Quantum Optics 1 course. It would be improved if copies of the lecture slides for lectures 3-5 were provided, along with solutions for Homework 1.
