Dans ce 45e épisode de Quantum, le podcast francophone de l’actualité quantique, Fanny Bouton et moi-même commentons ce que nous pouvons de ce qui se passe dans l’écosystème quantique. Et, champagne, c’est le 100e podcast quantique que nous enregistrons en quatre ans. En effet, il faut ajouter les 55 épisodes des entretiens Decode Quantum qui sont aussi en boîte. Et cela ne comprend pas tous les podcasts où nous étions invités deci delà.
Comme d’habitude, nous passons en revue l’actualité événementielle, scientifique, entrepreneuriale et des cas d’usage du domaine.
Et en voici le verbatim et les liens clés.

In the quantum computing realm, there’s often some confusion with simple technical lingua.
For example, in many general audience publications, you can read that ‘quantum cryptography’ is one application of future quantum computers. As a matter of fact, in a very distant future, quantum computers may break some RSA-based cryptography keys, but not create safer cryptographic systems. ‘Quantum cryptography’ is about creating shared encryption keys with quantum links that do not use quantum computers, and in most cases today, not even quantum entanglement, using the BB84 QKD protocol or one of its many variations. Quantum Key Distribution is indeed in the field of quantum cryptography. One right wording for the role of quantum computers here would be to associate them with ‘cryptanalysis’, the set of techniques used to break cryptographic security.

On September 29, 2022, I published the second edition in English of the book Understanding Quantum Technologies, probably the most comprehensive 360° overview of quantum technologies, including quantum computing, communications, cryptography and sensing. The monster document is about 1130 pages long. I publish it as free access PDF files in A4 and Letter formats that you can directly download here (no email or personal data asked!).
Amazon paperback edition
Like for the previous 2021 edition, the 2022 version is now available in paperback on Amazon. You can order it mostly anywhere in the world. It is released in two volumes of respectively 578 and 568 pages (vs 452 and 404 pages for the 2021 edition), both in Letter format. The two volume stack is 7 cm (2.7 inches) thick! It is a book of records with 920 illustrations, 4000 bibliographical references and a 400 terms glossary.
