Discussion Overview

The discussion centers around the recent release of the second edition of Ballentine's textbook, focusing on changes made, particularly the addition of a new chapter on quantum information. Participants explore the implications of these changes and their relation to earlier editions and foundational concepts in quantum mechanics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants note the addition of a new chapter on quantum information, questioning the specific content, such as the no-cloning, no-deleting, and no-hiding theorems.
  • There is mention of the sensitive issues discussed in the 1998 edition, with some participants expressing skepticism about whether the new edition addresses these issues differently.
  • One participant suggests that the new edition may be more akin to a third edition due to the significant time gap and evolution from the original 1970 paper.
  • Another participant highlights the availability of the mathematical prerequisites for free, suggesting it as a valuable resource for complex topics like continuous eigenvalues.
  • Some participants express curiosity about the preface of the new edition, which may provide insights into the author's motivations and the evolution of the material over time.
  • There is a light-hearted comment about the new edition shipping with "sexy pin-ups" of the founding fathers of quantum mechanics, indicating a more engaging presentation compared to the first edition.
  • One participant notes that the previous edition concluded with chapter 20, which covered Bell's theorem, and expresses interest in the content of the new chapter 21 on quantum information.

Areas of Agreement / Disagreement

Participants express a mix of curiosity and skepticism regarding the changes in the new edition, with no clear consensus on whether the new content significantly alters the discussions present in earlier editions. Some participants agree on the lack of clarity in the evolution of the material, while others question the coherence of the discussions across editions.

Contextual Notes

Participants reference the historical context of the textbook's editions and the evolution of ideas in quantum mechanics, indicating that the discussions may depend on interpretations of earlier works and the specific changes made in the new edition.

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?
