There is a story about quantum computing in yesterday's NYTimes. The story is particularly about superconducting qubits, which is my area of research, and quotes my advisor Rob Schoelkopf.
Michael Nielson provides an interesting discussion of the question “Can you give me a simple, concrete explanation of how quantum computers work?”: quantum computing for everyone
Finally, an article on a popular press site with a healthy dose of skepticism regarding D-Wave's announcement.
Incidentally, D-Wave has posted some details of their implementation on the arxiv. I have only had a chance to skim it so far, but I was amused to see that their readout scheme couples their qubits to an LC circuit, and they measure the phase shift of the resonator. This is an idea which has become increasingly popular after my lab demonstrated it in 2003 (Patrice Bertet published results for an harmonic oscillator readout of their flux qubits, and I understand that John Martinis' group has now coupled their phase qubits to a resonator).
Quantum computing is in the news today (such as this article which carries the dubious front-page text of "Quantum computers ready to go commercial", and here which is much more accurate) because Canadian start-up D-Wave demo'ed their 16-bit "quantum computer" yesterday. Quantum computer is in scare quotes in that sentence because their demo did not provide enough details to say one way or another whether their system is actually a quantum computer, because all they showed was some pretty graphics and solutions to problems which they claimed were being run on their hardware. It's going to take a lot more than that to appease the scientific community.
I think that what D-Wave is trying is pretty neat, but I am very skeptical at this point.
Update: Apparently D-Wave themselves are not willing to state with certainty that their machine is truly quantum. See the AP article on CNN.
