One interesting thing about quantum computing is that because it is a very new field, a large amount of the research in the field is on the arXiv (interestingly the worst users have historically been computer scientists.) Back in 2006 whenever I would sit around BSing about the arXiv with other quantum computing people, the idea of improvements that would bring the arXiv more up to date would come up. After hearing repeatedly about such ideas, in January 2007, I got fed up of hearing about these ideas and so I sat down and wrote scirate.com, a Digg-like front end for the arXiv. Okay well…

The arXiv is a game changer for how large portions of physics (and increasingly other fields) are done. Paul Ginsparg won a MacArthur award for his vision and stewardship of the arXiv (something other institutions might want to note when they decide that someone trying to change how science is done isn't really doing work that will impact them.) So...Given: The arXiv is great. But there is something that's always bothered me a bit about the arXiv: transparency.
(Note: those of you who wish to complain about the fact that you can't get endorsed on the arXiv, this article is not for you.…

Over 9 months ago I decided to apply for teaching tenure track jobs. Then the economy took what can best be described as a massive, ill-aimed, swan dive. Thus creating an incredible amount of stress in my life. So what does a CS/physics research professor do when he's stress? The answer to that question is available on the iTunes app store today: arXiview. What better way to take out stress and at the same time learn objective C and write an iPhone app that at least one person (yourself) will use?
What is arXiview? It is yet another arXiv viewer (there are two others available, last I…

Summary of what's new and happening on the arXivs according to voters on SciRate.
0807.4935 (15 scites) "Quantum Communication With Zero-Capacity Channels" by Graeme Smith and Jon Yard.
I blogged about this article here.
0807.4753 (9 scites) "Counterexamples to the maximal p-norm multiplicativity conjecture for all p > 1" by Patrick Hayden and Andreas Winter
One of the largest one questions in quantum information theory is the additivity of the Holevo capacity of quantum channels. The Holevo capacity of a quantum channel is the rate at which you can send classical information down this…

In attempt to keep my reading more current, I'm going to try to post the top rated arXiv papers on SciRate each week and hopefully add about the papers. Let's see how long I can keep it up (bets?)
0807.2668 (7 scites) "Mixing doubly stochastic quantum channels with the completely depolarizing channel" by John Watrous.
QP says: A large variety of open quantum system evolutions are describable using the superoperator formalism. A superoperator is a linear map from a space of linear operators to another space of linear operators. The ones we care most about in quantum computing are the…
