2012

22/03/2011: Our paper on Two-photon quantum walks in an elliptical direct-write waveguide array was highlighted today by the New Journal of Physics in the Highlights of 2011 collection: the second year running that one of our papers has been highlighted! “Selected by the editors, the sixty-four articles featured span some of the most cutting-edge areas of physics, and collectively represent the most cited, most downloaded and most influential articles published in NJP in 2011.” Many congratulations to Matthew, Jimmy, and both the teams at Macquarie and UQ, this is an outstanding result!
10/01/2012: Our paper on Conclusive quantum steering with superconducting transition edge sensors was published today in Nature Communications. Click on the pretty graphic to go to the UQ press release: This is our first paper with Sae Woo Nam and his wonderful team at NIST Boulder. Congratulations to everyone in both the UQ and NIST labs!
05/01/2012: Congratulations to Matthew Broome, winner of the Centre for Quantum Computation and Communication Technology Photographic Image Competition. Clever, artistic, and now proud holder of a $800 Apple voucher!

2011

13/12/2011: Congratulations to our long-time collaborator Sae Woo Nam who today was awarded the Department of Commerce Gold Medal, the highest honorary award granted by the Secretary of Commerce. A wonderful result and well deserved!
07/09/2011: Well it's been quite a year for the intersection of quantum and pop culture. A paper this week in Science by our former PhD student, postdoc, and much missed colleague Ben Lanyon, was mentioned today in a 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 computer chips pass key milestones; it contains a few colour comments by Andrew (who in his defence, did so late at night his time!).
13/07/2011: Our paper on Two-photon quantum walks in an elliptical direct-write waveguide array was published today in the New Journal of Physics in their Focus on Integrated Quantum Optics. It's the first collaborative paper between the experimental teams at UQ and Macquarie—congratulations to all!
10/06/2011: Holy heck! Our long time friend and QT Lab collaborator, Aephraim Steinberg, made the big time today, with the BBC's Now Show including a custom-written song about his recent paper in Science!
01/06/2011: There's a nice News Feature in Nature today, 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!
20/05/2011: A good day: our paper on Hardy’s Paradox and Violation of a State-Independent Bell Inequality in Time was also published today in Physical Review Letters. Congratulations to all, but particularly to Alessandro, two first-author papers in one day!
20/05/2011: Our paper on Experimental information complementarity of two-qubit states was published today in the New Journal of Physics. Congratulations to all!
05/05/2011: Andrew today was presented his 2010 Pawsey Medal by the Australian Academy of Science at Science at the Shine Dome 2011. It's been quite fun hearing talks from all branches of Science!
04/05/2011: The Register has an article on our compressive sensing paper from March, Oz boffins in quantum computing breakthrough. The article has thoughtfully been labelled NSFMP, i.e. Not Safe For Maths-Phobics ® .
11/04/2011: Andrew has been awarded a University of Queensland Vice-Chancellor's Senior Research Fellowship! A list of all the awardees can be found 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.

08/03/2011: In Germany, myScience also has an article on our compressive sensing paper: Quantum engineers remove roadblock in developing next-generation technologies. Despite the same title as the PhysOrg article, the text is different!
08/03/2011: Quick as always, today's PhysOrg has an article on our compressive sensing paper: Quantum engineers remove roadblock in developing next-generation technologies.
07/03/2011: Our paper on Efficient Measurement of Quantum Dynamics via Compressive Sensing was published today in Physical Review Letters. Click on the pretty graphic to go to the UQ press release:
Congratulations everyone, and hopefully one day all the co-authors can meet in person, preferably over a nice meal!
02/03/2011: Our paper on Matchgate quantum computing and non-local process analysis was highlighted today in the New Journal of Physics Best of 2010—“a special collection of papers that represents the breadth and excellence of the work published in the journal last year. The articles were selected for their presentation of outstanding new research, receipt of the highest praise from our international referees and the highest number of downloads last year.” Congratulations Sven, Alessandro and Aephraim, that's an outstanding result!
31/01/2011: Our paper on Single-photon device requirements for operating linear optics quantum computing outside the post-selection basis was published online today in the Journal of Modern Optics. Particular congratulations to Thomas, and thanks to the Australian Research Council who made this possible by awarding Thomas a Linkage Fellowship.
10/01/2011: Our paper on Violation of the Leggett–Garg inequality with weak measurements of photons was published online today in the Early Edition of the Proceedings of the National Academy of Sciences. Nice job everyone, and Mike, you're welcome back at any time!
05/01/2011: Our paper on Engineered optical nonlinearity for a quantum light source was published in this month's Optics Express (but has an official publication date of December 20, 2010—do we count this as a 2010 or a 2011 paper?). Congratulations Aggie and Alessandro on what I'm sure will be the first of many fruitful collaborations!
05/01/2011: Till's paper on Imaging of Trapped Ions with a Microfabricated Optic for Quantum Information Processing was published in this month's Physical Review Letters. Nice one Till!

2010

14/12/2010: During the Brisbane Writers Festival earlier this year, the ABC held a Café Scientifique. Ably hosted by Paul Willis, the topic was The Gloriously Messy Universe, which given the resulting conversation between Marcelo Gleiser, Tamara Davis, and Andrew White is a pretty apt choice of title...
We found out today that it will be broadcast on the Big Ideas program next month on Sunday 9th January (2pm WA, 4pm Q/NT, 5pm N/V/T/SA), and again on Thursday 13th January (3, 5 & 6pm). If the conversation sounds sharp and interesting, then much credit must go to Abbie Thomas and her team! (These programs will also be available after the broadcast date.)
1/12/2010: Andrew White has been made a Fellow of the American Physical Society. Goodness!
1/10/2010: James Owens has been awarded a honourable mention and a special prize for his oral presentation at the UQ Undergraduate Research Conference! Congratulations James, this is a great result that recognises all your hard work—enjoy spending the prize money!
23/09/2010: Our regulator collaborator Alán Aspuru-Guzik has been named one of the 2010 Young Innovators under 35 by Technology Review! Congratulations Alán! Video here in an awful embedded format. Slide the scroller at the bottom of the screen until you get to TR35 Session 2, Sep 23 2010, then enjoy. (Unless you're reading this via an iOS device, as the video is in flash—kinda ironic for a tech conference!).
14/09/2010: James Owens has been nominated to represent the Faculty of Science at the Inaugural UQ Undergraduate Research Conference. This is wonderful news and came entirely out of the blue: best of luck James!

23/07/2010: Well that was difficult! The posters at QCMC were simply superb, and after much discussion the judges came back to the Centres to ask for two prizes. It was Andrew's great pleasure to award these this afternoon to Stuart Szigeti and Stefanie Barz—many congratulations to you both!
19/07/2010: The Tenth International Conference on Quantum Communication, Measurement and Computation—QCMC to its friends—begins today at the University of Queensland. On behalf of both EQuS and CQC²T we're pleased to announce a Student Poster Prize for best presented and explained poster. We wish to stress that none of us are judges for the prize—or indeed organisers of the conference—so all bribes, compliments, complaints should be directed elsewhere ... see you at the poster sessions!
16/07/2010: Wonderful news for quantum science and optical science in Australia: seven years of funding was announced today for the ARC Centre of Excellence for Engineered Quantum Systems, the ARC Centre of Excellence for Quantum Computation and Communication Technology, and the ARC Centre of Excellence for Ultrahigh Bandwidth Devices for Optical Systems.

For funding junkies, here is the full selection report.
24/05/2010: Congratulations to Ben Lanyon who is a winner of the 2009 Dean's Awards List for Outstanding Research Higher Degree Theses. Very well deserved, and you can shout us all a drink the next time you're in town!
24/05/2010: Andrew was interviewed by Simon Lauder in The World Today, A few atoms bring quantum computing closer, about a nice paper published today by Michelle Simmons and her group in Nature Nanotechnology. For the very definition of eloquent, listen to his reaction when asked if this paper shows that the silicon approach is the one to put your money on (to be fair, he'd only had 2 hours sleep at that stage...)
11/05/2010: Our paper on quantum walks was featured in the Faculty of Science Photo of the Week, Photon Goes on Quantum Walk-about. Nice photo Matt! And scrolling down (insect, insect, insect ...) we found that we were also photo of the week back in January, Quantum Computer used to calculate the precise energy of molecular hydrogen.
15/04/2010: Our quantum chemistry has been highlighted as one of the Editors' favourite articles from the first year of Nature Chemistry:

19/01/2010: Hamish Johnston has a great article in Physics World, Quantum computer takes on quantum chemistry. The diagram is particularly nice!

17/01/2010: We've made the Mexican press, with an article at Milenio, Una computadora cuántica ya hizo cálculos. Alán translated his favourite part of the article for us:

The Australians! Wasn't that island an almost depopulated prison colony of England, when Mexico, still called New Spain, was proud of its Royal University, of scientists and researchers informed in physics and chemistry of the state of the art of the XVIII-th century?

A big cheery g'day from all us convicts to our Mexican readers! (Seriously though, our teams were funded by both the Australian and US governments, and are made up of folk from 8 nations across 4 continents: Australia, Brazil, Croatia, Iran, Italy, Mexico, the UK and the USA. Science is truly international.)

16/01/2010: The Palestine Telegraph has run Andy Extance's article in its Panorama Section.
15/01/2010: Andy Extance has a great article at Chemistry World, Quantum computer hits hydrogen bullseye. What a wonderful title! However Andrew wishes to say that he didn't concede, so much as stress, that a system with 522 gates isn't currently possible...

It was recorded by TVO and webcast. A big thanks to Australia's own Wilson da Silva for MC'ing, although he could have spared Andrew the "Crocodile Dundee" reference!
15/10/2009: Andrew was one of a 10-person panel discussing "The 10 Biggest Questions in Physics", at the Glenn Gould Theatre in Toronto. It was recorded by CBC's Quirks and Quarks—which, along with ABC's Science Show are the two longest-running science shows in at least the English-speaking world—and will be broadcast sometime in the New Year. A big thanks to Jim Handman and Bob McDonald who made the entire event a lot of fun!
01/10/2009: Our article on Complementarity in variable strength quantum nondemolition measurements has been selected for inclusion in IOP Select! What does this mean?

2007

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 Activity, 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.
30/09/2007: Well that just flew! After a 3 month visit, Dr Dr Thomas Jennewein is returning to 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 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 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 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.
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!
