Quantum Physics: A First Encounter: Interference, Entanglement, and Reality 1st Edition by Valerio Scarani | (PDF) Free Download

Description

Quantum physics is often perceived as a weird and abstract theory, which physicists must use in order to make correct predictions. But many recent experiments have shown that the weirdness of the theory simply mirrors the weirdness of phenomena: it is Nature itself, and not only our description of it, that behaves in an astonishing way. This book selects those, among these typical quantum phenomena, whose rigorous description requires neither the formalism, nor animportant background in physics.The first part of the book deals with the phenomenon of single-particle interference, covering the historical questions of wave-particle duality, objective randomness and the boundary between the quantum and the classical world, but also the recent idea of quantum cryptography. The second part introduces the modern theme of entanglement, by presenting two-particle interference phenomena and discussing Bell’s inequalities. A concise review of the main interpretations of quantum physics isprovided.

User’s Reviews

Reviews from Amazon users which were colected at the time this book was published on the website:

⭐A superb introduction to interference and entanglement as the key feature in quantum physics. Especially entanglement. And also a look at the quantum classical boundary if there is one – which includes a discussion of ‘measurement’ and of Everett’s astonishing hypothesis of macro superpositions. The author clearly has deep expertise and experience along with a superb ability to explain things as simply as possible. No math! An unfortunate publishing rule it would seem. Just a little would have improved the exposition even more. Or maybe not. Lots of historical contexts and insight. A few personal ideas. Just excellent.

⭐This is probably the first 100 page book that I ever bought at this price. Valerio Scarani has presented a goodapproach to several of the mysteries of quantum mechanics (QM) based on actual experiments. I didn’t really knowthe basis of quantum cryptography (not that I was searching for one) but he explained it well. The ideas presented inthis book are verbal explanations that one can keep in mind when studying QM in more depth.

⭐I’ve looked at a lot of basic books on quantum theory. This is the best one I’ve seen so far. It does a remarkably good job of giving newcomers an insight into the phenomena or interference and entanglement, all the more so given that there’s almost no math in the book. Scarani is a serious researcher in his own right, but this book makes clear that he is also a gifted teacher.BTW: ignore the one-star review. It’s not Scarani’s fault that the customer didn’t get his copy of the book.

⭐I did some quantum computing work and became very interested in quantum physics as a result. This book is a very good starting place. It’s wonderfully written and very clearly presented. It explores the various experiments that lead to our current understanding (or lack thereof) of quantum physics in a very effective way – the author takes you one step at a time, leading you through the same thought processes that the scientists designing the experiments went through. It’s a very nice balance of history, story-telling, and science. I highly recommend it.

⭐My compliments to the translator who did a fairly decent job. In the whole book there are only about 20 sentences that are grammatically awkward. The author himself does a fairly decent job as well. His technique is to explain quantum phenomena through interferometry experiments. This allows him to avoid all mathematics and yet, still get his point across. An enjoyable read.

⭐Quantum Physics: A First Encounter: Interference, Entanglement, and Reality by Valerio Scarani is a very readable and informative introduction to quantum physics. The book has several notable strengths. Firstly the reflective didactic method that engages the reader and conveys clearly the fundamentals of the subject. Secondly, as opposed to several other popular expositions on the subject, Scarani conveys the extraordinary novelty and significance of non-locality. Additionally, there is a refreshingly detached attitude to the subject’s intrinsic significance. Rather than the common unscientific triumphalistic assertions of the completeness and unassailability of quantum physics, Scarani emphasises the intrinsic limitations of what can only be descriptions of reality, and the need to maintain a sense of wonder and openness to phenomena. Finally, the book is short, and hence practically readable.CR French

⭐I would not give this a five star rating only because it is not PERFECT! I actually intend to give it a 4 1/2 rating in fact.I liked this book for four things: 1) This is such a small book. (Lesser the words one speaks, the better to listen). 2) No technical blabbering, but STILL maintains clarity of concepts. 3) Tells about real experiments. 4) One of the latest on the old subject (as of July 2006!).Now to give an example of the minor defects that I noticed – The Unbalanced Franson’s Interferometer explanation could leave the novice reader confused as to why the tiny time difference could not lead to distinguishability. There is nothing in the main text that even hints about this.All in all, this is a MUST BUY for all ‘physics-maths’ kind of people who have are new to QM.

⭐A clear and concise exposition of the basics, but even so a little technical for this bear of little brain.Understandably a major headache for the translator.The interferometer diagrams were original but exceptionally clear.Does what it says on the cover.
