I published the 2025 edition of the ebook “Understanding Quantum Technologies” on September 29th, 2025. Since then, I regularly updated it with news, mostly related to new arXiv preprints. The update log is at the end of the book.
Like with each past editions since 2021, I wait about a month of beautifying and then publish the book on arXiv. The goal is to extend its “distribution” to a broader scientific audience.
It is now available on https://arxiv.org/abs/2111.15352, with the full version in Letter format, now containing 1,522 pages.
I will still continue to update the book on this website and provide it in multiple formats: A4 and Letter, full version, of full version split in 5 parts, and a key takeaways version of 36 pages in both A4 and Letter formats. I always recommend readers to download the last edition of this book.

In October 2025, Google announced the publication of a paper in Nature on a “verifiable quantum advantage” with “Quantum Echoes”. I like the name. It reminded me of one of my preferred Pink Floyd song, from the Meddle album, released in 1971!
Google’s announcement was widely reported in social networks and the media as a breakthrough event. This was completed by the publication of an arXiv preprint with a use case to determine the structure of two simple molecules. But here, we are not at all in a quantum advantage regime.

Ce 73 ième épisode de Quantum, le podcast de l’actualité quantique, fête les 6 années de ce podcast. Avec Fanny Bouton, nous faisons comme d’habitude le point sur l’actualité quantique.
Voici la version texte et les liens utiles du podcast:
Sortie de la 8ième édition de Understanding Quantum Technologies
Comme le nouvel iPhone sorti il y a quelques semaines, c’est la meilleure version de tous les temps ! Tout son contenu a été mis à jour, sur tous les plans, scientifiques, technologiques, fournisseurs et écosystèmes. C’est votre Hitchiker’s guide to the quantum galaxy ! Cette version adopte un nouveau format et une nouvelle présentation grâce à une migration fastidieuse de Word vers LaTeX.
