Please take a second to learn about BlogSenseWP (http://tinyurl.com/ycpajog).

BlogSense is a content & automation tool for WordPress. (I know there are a ton of them on the market, but BlogSense has been in development for about 8 months now and is finally in a position to compete and out perform the big boys.) Not only does it lead the market in features, and content sources, it provides a members only community that’s frequently updated with the fresh material relevant to automation and internet marketing.

Thanks for your moment,

]]>Hence my admiration and appreciation for bloggers like Scott Aaronson, Dave Bacon, Terry Tao, Dick Lipton, the Fortnow/Gasarch team, Michael Nielsen, Igor Carron, Gil Kalai, the Secret Blogging Seminar, and the (many) financial engineers at Wilmott … to name just some of the hard-working bloggers who (IMHO) deserve everyone’s thanks.

]]>Very, very funny post and follow up comments.

Professor Sidles, I’m glad to see you linking to your “what’s new” department page, but I still recommend a blog that more like your comments here.

]]>IMHO, it would be interesting (and a service to the community too) if these often-voiced sentiments were fleshed-out with specific instances.

For example, when we say “the feeling is”, whose feelings are we talking about? The feelings of algebraists? The feelings of geometers? The feelings of complexity theorists? The point is that quantum theory is so protean (in its mathematical, physical *and* engineering aspects), that there is plenty of room for very different perspectives regarding the D-Wave/Google enterprise.

My own perspective on the uneasy relation between the engineering-style research of D-Wave/Google, and the logician-style research of academic QIT/QIP, is very much summed-up by one of the classic Great Truths: *“It is one of the chief merits of proofs, that they instill a certain skepticism about the result proved”* (Russell).

Or as von Neumann said it (at greater length), in his 1947 essay “The Mathematician”: *“There is a quite peculiar duplicity in the nature of mathematics … much of the best mathematical inspiration comes from experience … [this requires] the re-injection of more or less directly empirical ideas.”*

Thus, it might perhaps be rigorously proved that (under some definitions) the D-Wave device is not a “quantum computer.” And yet it would show no disrespect for complexity theory, if this led us to wonder whether we might broaden our conception of what quantum computing is, and therefore, what quantum computers are, in response to the D-Wave/Google’s stimulating “re-injection of more or less directly empirical ideas.”

Conversely, it is evident nowadays that rigorous QIT/QIP theorems are serving equally to narrow and broaden the domain of discourse … both of which are good.

In summary, it seems (to me) that the D-Wave/Google work is broadening the domain of QIT/QIP discourse, in a way that (eventually) will benefit the most rigorous logicians, the most skilled hardware-builders, *and* the most ambitious entrepreneurs.

*ALL* of which is good! On which note, best wishes for a a Happy New Year are extended to everyone! ðŸ™‚

]]>I have no objection to that at all. Unfortunately, the feeling is that they are promoting themselves at the expense of QC technology.

]]>The point is, it’s not clear that D-Wave’s device is most naturally described in terms of qubits. It seems plausible (to me) that the D-Wave device can more usefully be viewed as an analog computer, which (possibly?) achieves its speedup by operating in a state-space that is larger-than-classical, but smaller-than-Hilbert.

Everyone is familiar with the derivation of high-accuracy asymptotic expansions by deforming integral paths into the complex plain. Integral approximations that work poorly on the real axis, can work exceedingly well when they are extended in the complex plane.

By analogy, perhaps D-Wave/Google have shown that analog annealing methods can work better when they too are extended into complex state-spaces?

That is why it seems plausible (to me) that there is plenty of good math, science, and engineering to be found in this new quantum territory that D-Wave/Google are exploring.

It is clear that exploring this new quantum territory requires rather different tools (in terms of math, science, and engineering) from what the QIT/QIP community are accustomed to … and in the long run, perhaps this novelty will prove to be a good thing.
