AI Thread Summary
A new second edition of Ballentine's textbook has recently been released, featuring an additional chapter on quantum information, although details on changes are limited due to the absence of an Amazon "look inside" feature. The discussion highlights that the new edition does not significantly alter the sensitive topics covered in the original 1998 edition, which was based on Ballentine's earlier 1970 article. The new edition is described as more akin to a third edition, as it follows the 1990 and 1998 editions. The preface, available for free on the publisher's website, offers insights into the author's motivations and the evolution of the content over the years. The previous edition concluded with Bell's theorem, while the new edition adds a chapter 21 focused on quantum information, prompting curiosity about its content.

For those who like Ballentine's textbook, I just noticed that a 2nd edition has become available very recently. Unfortunately, it doesn't have the Amazon "look inside" feature enabled so I can't see easily what's been changed, apart from the extra chapter on quantum information mentioned in the general blurb.

Amazon has 4 copies left... but... <click>... now they have 3. ;)

A new chapter about quantum information?
No-cloning no-deleting no-hiding theorems maybe?

The new edition ships with sexy pin-ups of the founding fathers of QM, which was always lacking in the first edition.

We've always discussed the sensitive issues from his 1998 book, like we do right now here: https://www.physicsforums.com/threads/living-opponents-of-the-copenhagen-interpretation.781071/
Istm, what's discussed is a somewhat incoherent mixture of his book, and his old 1970 paper.

I don't think this 2nd edition changes anything there, but it would be interesting to know exactly, nonetheless. I mean the 1998 book was built on his 1970 RMP famous article (quite a gap).
This is more like a 3rd edition. The 1st was 1990 (with a different publisher?), the 2nd was 1998 (World Scientific), and now we have the 2015 edition (sic) -- which World Scientific seems to call the "2nd edition" of his 1998 book.

It's interesting to read the preface (which can be freely downloaded as part of the "front matter" on the publisher page that Dr Claude gave). It gives some insight into his motivations back in 1990, as well as how it has evolved in ~25 yrs since.

That's true.

His book evolved a bit from the 1970 paper where in the book he clarified exactly what an observation selecting from a conceptual ensemble means.

Thanks

The previous edition ended with chapter 20 (Bell's theorem and its consequences.
There is now a new (21) chapter about quantum information.
Did somebody read it?
