Our Objective:
To explore quantum mechanics with technologies that exploit the unique properties of quantum
information.

Super-Vision for Mr. Shrimp.
- 20/06/2008: Andrew's profile is being featured on the front page of Nature Asia this week.
- 24/05/2008: There is a simply wonderful write-up of our shrimp paper by Andrew's favourite blogger, PZ Myers of Pharyngula fame,
The superior eyes of shrimp. (And yes, he was Andrew's
favourite blogger even before he wrote about our paper!)
- 23/05/2008: The New York Times reported on our shrimp paper! See
A different viewpoint in the Science Section.
- 20/05/2008: Jeepers creepers! Scientific American reports again on the shrimp paper,

- 19/05/2008: Well we're tickled pink that our shrimp paper has made been reported in the National Geographic, or at least
their website! See,
"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
listen!
- 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
UnderwaterTimes.com, Scientists: Mantis Shrimps See Beyond The
Rainbow; 'A Completely New Concept Of Polarization Vision'; at Scientific Frontline,
Scientists find weird shrimp has astounding vision; and even at
The Today Show, Giant shrimp can see beyond the rainbow.
- 14/05/2008: Well that's nice! Our paper on optimal polarisation vision in shrimp is
the number one pick in the blog by the PLoS ONE online
manager, A blog around the clock.
- 14/05/2008: Our paper on
The Secret World of Shrimps: Polarisation Vision at Its Best appeared today in PLoS ONE. Weird little beasties they are!
- 20/05/2008: Jeepers creepers! Scientific American reports again on the shrimp paper,
Mantis Shrimp Has Built-In Shades.
- 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
Scientific American.
- 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!)
- 26/02/2008: Today's PhysOrg has a nice article on our qubit-qutrit experiment:
Physicists Demonstrate Qubit-Qutrit Entanglement.
- 14/02/2008: Our paper on
Manipulating Biphotonic Qutrits appeared today in Physical Review Letters: who said scientists aren't romantic?
- 03/01/2008: Dr Michael Goggin from Truman State University, has started a
six-month sabbatical with the QT Lab, hot on the heels from one with Prof. Paul Kwiat at Illinois. Welcome Mike!
- 19/12/2007: Happy Eid ul-Adha! Our paper on
Experimental 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 quantum.info/shors.
- 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 Agency,
IARPA, not by DARPA. It's easy to see how these things can get confused!
- 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 first ever quantum calculation.
- 8/12/2007: There's a nice article by Davide Castelvecchi on our Shor's experiment in today's
Science News.
- 30/11/2007: An article has appeared in today's
Innovations Report on our
forthcoming Physical Review Letter on an Experimental demonstration of Shor's algorithm with quantum entanglement.
- 17/10/2007: Happy International Dadaism month! Marco's paper on
Effects of frequency correlation in linear optical
entangling gate operated with independent photons appeared today in Physical Review A.
- 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
Brisbane Times,
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!
- 14/9/2007:
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 occassion 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 midnight...)
- 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.
- 20/7/2007: After a successful (and amazingly quick) year, Devon Biggerstaff has finished his Fulbright and is starting a PhD
with Kevin Resch at the University of Waterloo. Good luck Devon, and come back soon!
- 15/6/2007: Happy Magna Carta Day! In PhysOrg today there's a nice interview with Kevin Resch,
Super resolution phase measurements – without entanglement.
- 31/5/2007: Happy Vesak! Our paper on
Time-Reversal and Super-Resolving Phase Measurements appeared today in Physical Review Letters.
- 16/5/2007: Happy Dunghri Mela! Our paper on Entanglement Generation by Fock-State Filtration appeared today in Physical Review Letters.

Nathan!) is leaving us to work as a Postdoctoral Scientist at the University of Vienna. Good luck Nathan, and thank
you for all the fun!
