tweet by Stephen Fry!
Congratulations Ben on both the superb paper, and the call-out by Stephen Fry—is this the modern British equivalent of being recognised by royalty? ☺
- 01/09/2011: There's a story today in New Scientist on a nice recent paper by Mariantoni and colleagues at UCSB,

Quantum computing: The power of discord. It looks at recent work on quantum
discord—a newish kind of quantum correlation—including our paper experimental paper from 2008. Definitely worth a read! One important correction: the
opening line of the article makes it sound like I built our experiment, when of course the hard yards were done by Ben, Marco, and Marcelo—all congratulations
are due to them!
- 25/05/2011: Our collaborator Alán Aspuru-Guzik gives an interview at physicsworld.com,
Quantum computers tackle chemistry and biology. Go check it out, it's only 4 minutes long and does a
nice job of explaining why we find our work on quantum simulation so compelling!

in this nice article on cleaning up mining waste using bugs.
- 16/03/2011: Well this is interesting: according to a paper in the arXiv today, the best city in Australia for physics—by quite a ways it turns
out—is Brisbane. The paper identifies which cities worldwide produce more excellent papers than can be expected. The idea is that:
...if excellent papers are defined as the top-10% most-highly cited papers in a field, on the basis of the null hypothesis a value of 10% of all papers published from
a city would be expected as belonging to this category.
The authors then calculate the standardized residual for every city in the world in 2008 that published a top-10% paper, using
Z=(observed-expected)/√expected (Z=1 indicates the city is publishing the expected number of
top-10 papers). They note—and I'm sure we all heartily agree!—that:
From a policy perspective, it may pay off for the sciences within a country to identify (by these visualization methods) and expand regional centers of excellence (for
example, with specific financial support). In our opinion, one should not subsidize size, but those centers should be fostered where the observed number of excellent
papers exceeds the expected numbers.
And the results for Australia in Physics? <drum-roll> Brisbane, Z=4.1; Adelaide, Z=3.1; Melbourne, Z=2.7; Sydney, Z=2.5, and Canberra, Z=1.4.
- 08/03/2011: And TG Daily also has an article on our compressive sensing paper:
Quantum engineers clear a roadblock in
developing new technologies. I love the editorial at the end of this article:
If you are a technology enthusiast you might find yourself interested enough to want to read it. You won’t be able to though because you have to have a subscription to
read the journal. That may be a bummer but the future of academic journals is creative commons licenses. Scientific information like this will become more widely
available to the public sooner rather than later.

"Weird Beastie" Shrimp Have Super-Vision.
- 19/05/2008: Well that was fun! Andrew was just interviewed about the shrimp by
Red Symons for ABC Melbourne's morning radio show. Best, and most unexpected,
question: "What would you do if you had genital-fingers?..." :)
- 17/05/2008: Sonja's got a great interview with Bob McDonald on the Canadian radio show, Quirks and Quarks,
Mantis Shrimp's Super Sight, have a
- 15/05/2008: ...And now there's a Softpedia article on our shrimp vision paper,
Shrimp See All Types of Polarized Light. It's nicely
written, but gets the same quote wrong as the Physics World article ... hmm!
- 15/05/2008: Gosh, a lot of people are interested in shrimp. There's an article in today's Science Daily,
Weird Shrimp Has Astounding Vision, a lovely and comprehensive
article in today's Physics World and Optics.org
(although they do get one quote wrong!), Shrimp see a polarized world, and even a report in MSNBC,
Giant shrimp can see beyond the rainbow.
- 14/05/2008: There's an article on our shrimp paper in the Nature blog The Great Beyond,
Shrimp's super sight (also see the
Scintilla link); at The Press Association,
Shrimp with super-vision revealed; at

- 13/05/2008: There's a nice article in the Discover magazine blog on our shrimp paper,
Freaky Shrimp Species Has Singular
Sight, and in Reuters,
Shrimp can see beyond the
rainbow, which has also been picked up by
- 24/04/2008: We seem to be tickling Dave Bacon's title bone, he once again
quite likes the title of one of our recent arxiv
papers, this time The secret world of shrimps: polarisation vision at its best. (He also thinks it's fascinating, which again is nice!)
- 23/04/2008: Today's Nature Photonics features our qutrit-qubit experiment in a very nice Research Highlight,
Higher-level control, doi:10.1038/nphoton.2008.39.
- 04/04/2008: Today's Physics Arxiv Blog has a nice discussion of our higher dimension quantum computing paper: Qutrit breakthrough brings quantum computers closer.
- 03/04/2008: Dave Bacon (aka the Quantum Pontiff) quite likes the title of our recent arxiv paper Quantum
computing using shortcuts through higher dimensions. (He also likes the paper as well, which is nice!)

demonstration of Shor's algorithm with quantum entanglement appeared today in Physical Review Letters.
- 15/12/2007: Despite what you may
read, quantum computing will
not enable anyone to transmit information faster than the speed of light. You can find an overview of our experiment and its possible implications at
- 14/12/2007: ZDNet in Asia and
Australia have an article our on
Shor's experiment. Some corrections: it's more correct to say that the information needed to describe n entangled qubits grows exponentially, not the
number of states; and we are funded in part by the Intelligence Advanced Research Projects Activity, IARPA, not by DARPA. It's easy to see how these things can get
- 14/12/2007: Cool! Our work our Shor's experiment made it into Neatorama!
- 11/12/2007: Today's PhysOrg has a nice article on our Shor's experiment: Physicists perform the

the University of Vienna. See you next year Thomas!
- 26/9/2007: Great news! Our Discovery Project on "Biomolecular optoelectronic materials and
devices" has been funded by the Australian Research Council. Roll on cold black photon counters!
- 18/9/2007: Gosh, more coverage! There's an article about our paper on Shor's algorithm in today's
Sydney Morning Herald and
The Age. As we say below, our experiment is
interesting in that it demonstrates every stage of Shor's algorithm, particularly the entangling step. It is not scalable in itself, but there is a in-
principle path to scalability which we and our colleagues are investigating to see if and when that's going to be feasible. As Ben Lanyon says "it was incredibly
hard to do" ... so RSA Security don't need to worry just yet!
Despite the title of today's Ars
Technica article, we'd just like to make it clear that we have never burnt through any graduate students, although we have on occasion fed them too much
coffee. (Indeed, working in a dark lab we try not to let our researchers near bright light, get them wet, and most importantly, never feed them after
- 14/9/2007: The Register in the UK have a slightly breathless view of our Shor's
paper. Our work does not pose a threat to current, everyday, cryptography, since the time scale for such quantum computation is closer to decades than months,
and may not even be based on our research! It's just too early to tell for sure. You only need to worry about quantum computation today if you are prime-number
encrypting and publicly sending messages that you still want to be secret 20 years from now (i.e. you are paranoid or a government ... ahem.) On the other hand, this
is the first time our work has been directly compared to a James Bond film ...
- 13/9/2007: Well that didn't take long! Slashdot covers the New Scientist article
which covers our arXiv paper which is still with the referees...
- 13/9/2007: In today's New Scientist there is an article,
Quantum threat to our secret data, prompted in
part by our recent arXiv paper, Experimental demonstration of Shor's algorithm with quantum entanglement. It's probably
far too soon to talk about threats! What's interesting is that our experiment demonstrated every stage of Shor's algorithm. It is not scalable in itself, but
there is a in-principle path to scalability which we and our colleagues are investigating to see if and when that's going to be feasible.
- 12/9/2007: There's a nice write-up of our work in today's New Scientist blog,
How a quantum computer factorises numbers, which says
"Today, New Scientist reveals details of a device that may go down in history as the forerunner of the quantum computer." Gosh!
