A Brief overview of the course “Quantum Computing for the absolute beginner” in Udemy.

I took the course in order to learn more about the topic, and also to test the platform.

https://www.udemy.com/qc101-introduction-to-quantum-computing-quantum-physics-for-beginners/

Strengths:

Very didactic explanations, very well produced videos.

Simple and enlightening explanation of quantum cryptography (or rather, shy it is unbreakable by his own nature).

It has few formulas, it is really an introduction.

It shows the main points, and bit of quantum logic gates.

Another really cool thing is a demonstration of Visual Studio Q# (a simulator) and IBM Q experience (a true quantum computer).

It has a certificate (it is good because it is very common to abandon these on-line courses).

Negative points:

There are not exercises between lessons or evaluations at the end of the course.

It is a very basic introduction, does not enter the most popular algorithms as Deutsch-Jozsa, Grover or QFT.

Conclusion:

It delivers what is proposed, an introduction with a minimum depth on the subject.

It has 3.5 hours of video, and costs around $ 10.

To explore a very hard level, you have to go to the same physical book:

Quantum Computation and Quantum Information, Nielsen & Chuang
Quantum computation Explorations — Colin Williams
Feynman Lectures on Physics — Vol III — Richard Feynman
