Here is Understanding Quantum technologies 2023, the 6th edition of this book and the third in English. As all my book, it is a free to download book without any questions. It beats another record of mine with 1,364 pages, split in three volumes for e-readers and a future paperback edition on Amazon.
It is probably the most thorough book on the matter covering so many dimensions (history, science, technology, hardware/software, usages, societal, political) and for all quantum technologies (computing, telecommunications, cryptography, sensing, quantum matter). It is a very large book but it can also be considered as a collection of more reasonable books: one on quantum physics (140 pages), another on quantum computing hardware (344 pages), one on quantum computing programming, software tools and case studies (270 pages), yet another one on quantum communication and cryptography (94 pages), on quantum sensing (49 pages, we are here in the “novel” format), on quantum geopolitics (99 pages), a directory of quantum industry vendors (665 are described in the book), etc. But they are all tied together in a consistent manner![...]
