I have decided to try to make a return to blogging and I am intending to write new posts about once or twice a week. Making a statement like this is dangerous, as veteran bloggers know well, as it usually leads to several month’s radio silence. Nevertheless, I hope that making this announcement will give me enough motivation to actually go through with it.
For those of you who are not up-to-date with the latest Matt Leifer gossip, I essentially gave up blogging at the end of 2007 because I came down with a mysterious illness that, amongst other things, ruined my ability to do anything that requires concentration. I had to take an indefinite leave of absence from work in April 2008 and I can attest that this is not a fantastic thing to do for your academic career when you are still a postdoc. I have since been diagnosed with Chronic Fatigue Syndrome, a controversial syndrome that does not have any very effective treatments (at least none of them have really worked for me so far). Although I am not really feeling any better, I have decided to try and work part-time for a couple of days a week and I am in the process of transferring the remainder of my FQXi grant to University College London to pay my salary for about eight months.
As you can imagine, I have built up a lot of internal rants about quantum theory in the couple of years since I stopped blogging, so I do not think I will have much trouble coming up with topics to write about. One person who should be especially glad about my return to blogging is Chad Orzel, because it means that I will have far less time to write overlylongcomments on his blog whenever he writes something about that touches on the foundations of quantum theory.
Unfortunately, however carefully crafted your search is, quite a lot of quantum nonsense will always make it through, so I usually just ignore links with suspect titles. Recently though, the feed has been turning up a lot of links with titles like “Quantum Physics and God”, so much so that I was eventually tempted to click through to see what all the fuss was about. It turns out that these articles were all referring to a new book Quantum Gods: Creation, Chaos, and the Search for Cosmic Consciousness by Victor Stenger who is perhaps best known for his nu athieism book God: The Failed Hypothesis. How Science Shows That God Does Not Exist. Amongst other things, the new book is aimed at debunking the claims of the quantum mystics.
For a long time, I have thought that a book that clearly sets out the case against the quantum mystics is a good idea. I don’t imagine that many people who actually believe in this stuff will read the book, although some may get drawn in by the fact that the title does not suggest that the ideas are going to be debunked. More importantly, however, this is ammunition for scientifically literate people, who may not be well versed in quantum theory, to use when they come up against quantum nonsense.
I have not read the book yet, and I am unlikely to do so in the near future due to my current illness. I would like to add it to my carefully curated Amazon Store of books about quantum theory, but I have a policy of not including any books that I haven’t read, since there are a lot of bad expositions of quantum theory in the popular literature. My main concern is whether Stenger manages to clearly separate the argument against quantum mysticism from his more general concerns about whether or not science is compatible with new age mystical beliefs. In my view, it is one thing to hold a set of new age mumbo jumbo beliefs and quite another thing to believe they are supported by quantum theory. The latter is clearly false, independently of the general debate about new age ideas. For one thing, a large part of the message of things like The Secret and What The Bleep… seems to be that you can make good things happen by the power of positive thinking. I can certainly imagine that this is true to an extent in the realm of human affairs, but that is a matter of psychology and sociology rather than quantum physics. I am encouraged by the fact that Stenger is also the author of a 1997 article from the Skeptical Inquirer, which was my previous go to link for people in need of some quantum debunking. Since I think this is likely to be an important book, I may decide to relax my policy and add the book anyway, provided enough of my trusted colleagues and commenters tell me that the book is accurate. So go out and read!
I’ll leave you with a confrontation between Richard Dawkins and Deepak Chopra, which I couldn’t resist adding to this post.
‘Tis the season to get employed as a foundations researcher. Perimeter Institute is currently advertising vacancies for Junior Faculty positions in Quantum Foundations. See here for more details. Deadline for applications is Jan 15th.
It seems that this blog is becoming the official website for Quantum Foundations job announcements. Sadly, in the current climate this still means that I don’t have to bug you with job adverts too often. In any case, there are two postdocs available via the PIAF (Perimeter Institute — Australia Foundations) partnership, which look like a pretty sweet deal for any finishing postdocs/grad students in Foundations. They involve spending 9 months of the year in Sydney and 3 months here in Waterloo. Theoretically, this means that you could completely avoid experiencing winter for the three years of the postdoc. The job ad is posted here and the deadline is 7th December 2007.
It’s not often that I get to write a post with a title like this, but right now there are two opportunities worth mentioning. Firstly, if you are a student looking for a Ph.D. position in foundations then Caslav Brukner has one available in Vienna. The advert is attached below.
Secondly, the application process for the next round of fqxi grants now appears to be open. I haven’t received an email from them about this yet, but I just noticed that the form was up on their website. They have funded quantum foundations projects in the previous round, along with projects on many other foundational questions in physics.
OK, here is the Vienna advert:
PhD position in the group “Quantum Optics, Quantum Nanophysics, Quantum
Information” (www.quantum.at) at the Faculty of Physics, University of
Vienna is available immediately. The student will undertake research on
the foundations of quantum physics and theoretical quantum information
in collaboration with Prof. Caslav Brukner
(http://homepage.univie.ac.at/Caslav.Brukner/).
Candidate is expected to have an undergraduate degree in Physics, Maths,
Computer Science or Engineering. She/he will be able to work
independently and collaboratively. Interest to work on foundations of
physics and experience in quantum theory and/or information theory will
be advantageous. Enthusiasm will be essential.
The position is supposed to be fully integrated into the Doctoral
Program “Complex Quantum Systems” (www.coqus.at). Applications, prepared
to meet the standards (http://www.coqus.at/index.php?id=333) of the
application to the CoQus Doctoral Program, should be sent to Canan
Goeser (Secretary) (canan.goeser@univie.ac.at).
The position is funded by the FWF-Project “Quantum Information:
Foundations and Transition to Classicality” of the Austrian Science Fund
(FWF).
According to Wired, one of id Quantique‘s quantum cryptography systems will be used to transmit votes securely from voting machines in Geneva in the upcoming national election. This is certainly good PR for quantum crypto, especially given the security issues surrounding the use of automated voting machines. Maybe I’m missing something though, because I thought that the main security problems had to do with the possibility of hacking the machines themselves rather than with the transmission of votes. Public key crypto would probably have been just as good in practice, unless the Swiss government believes that someone in the locale has built a quantum computer.
I think I might have mentioned before that von Neumann is a bit of a hero of mine. I transferred my affections from Feynman as soon as I was old enough to realize how much exaggeration must be involved in the “Surely you’re joking” stories. Sure, von Neumann may have made a mistake about hidden variable theories, but we are talking about a guy who gave us the first rigorous formulation of quantum theory, made major contributions to game theory and invented the modern computer architecture, so I’m willing to cut him some slack on that point.
Anyway, I thought I’d just mention the workshop at Princeton to mark 50 years since von Neumann’s death and 75 years since the publication of his book on quantum theory. Looks like there were many interesting talks.
There is an opportunity for a graduate student to visit Perimeter Institute for a 3 month period to work with me on a technical project in Quantum Foundations. The main idea is to give students who are interested in quantum foundations, but working in other fields for their grad studies, the opportunity to take a break and think about quantum theory seriously for a short period. The position is funded by FQXi under my project “Abstract Quantum Probability” and the project would be selected by mutual agreement from one of the topics covered by the grant.
Funding will be provided, but the exact amount depends on Canadian immigration issues, i.e. we can only provide subsistence expenses (travel, accommodation and a per-diem for meals) to non-Canadian residents. The visit can take place at any time during the year, depending on what is most convenient for the student and myself.
If you are interested then please send your CV, a short (one or two paragraph) explanation of why you would like to visit PI and a letter of recommendation from your advisor to me at this address. There is no official deadline for applications and the search will continue until a suitable candidate is found. However, I expect there will be enough applications to make a decision by the end of September.
For further details of the possible areas of research for this project, please see the reading list below.

Since I get asked a lot, I have added a collection of links to resources on quantum foundations to the About page. Any suggestions for additions will be gratefully received, especially if you know of any good quality popular talks that can be viewed online.
P.S. In case you were thinking of asking, neither “The Tao of Physics” or “What The Bleep Do We Know?” are ever going to be added.
