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!).

  • 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!

We should get T-shirts made), and his team at Bristol, where they have repeated our 2007 Shor's algorithm experiment, replacing the free-space circuitry with integrated-optics. There's comments from Jeremy—of course!—and also from Dan Browne and Andrew, who were authors on the two earlier Shor papers.
  • 28/08/2009: There's a great article today in The Quantum Times on Quantum information for chemistry and biology by Alán Aspuru-Guzik, which is a lovely intro—and I'm not just saying that because it briefly mentions our work!
  • 25/08/2009: Ross McKenzie has a blog entry on Andrew's talk today at the CQIQC III in Toronto, entertainingly titled James Bond meets Niels Bohr. Nice one Ross!

  • 18/06/2009: Ben Lanyon is the subject of a nice article today by Machines Like Us, "A quantum leap". (I've often wondered when people use this expression—do they realise it can refer to the smallest possible leap?). Look for the cool photo and the even cooler description of banging things!
  • 24/04/2009: Our collaborator Alán Aspuru-Guzik was interviewed today in the Nature blog, The Sceptical Chymist and discussed our recent work on quantum chemistry on a quantum computer. Cool!

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 here.
  • 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!

1999

  • Nov 1999: Beginning the construction of the first Quantum Technology Lab.

  • The old wood-working shop:


    Yep, that's a floor:


    Lab this side, work shop that side:


    The start of the reincarnation of the red hardwood floor from unappreciated workshop surface to polished display floor in a refurbished house. Reduce, reuse, recycle!


    Some hours later, almost done...


    ... except, oh look, several tonnes of rough concrete that needs to be removed by hand ... that's a surprise!


    Some days later, several tonnes of rough concrete ready to be trucked away.
