Research in the Quantum Technology Laboratory is aimed at exploring and exploiting the full range of quantum behaviours—notably entanglement—with an eye to engineering new technologies and scientific applications.
- 16/05/2013: For those of you interesting in all things quantum computing, go read Scott Aaronson's blog post D-Wave: Truth finally starts to emerge. The tl;dr version: good news. It's finally possible—modulo some reasonable assumptions—to infer the presence of entanglement in a D-Wave device, athough not what kind, or how much. bad news. D-Wave have showed no speed advantage whatsoever for quantum annealing over classical simulated annealing. terrible news. D-Wave's egregious hype is very destructive.
- 02/05/2013: Andrew provided comments to the ABC on the excellent paper by Sven Rogge and his team published in Nature today, Positive spin in quantum discovery. Congratulations Chunming, Sven and the rest of the team!
- 04/04/2013: Our Vice-Chancellor, Professor Peter Hoj, was on ABC Radio this morning reporting that UQ Scientists receive Australian Academy of Science Fellowships. Have a listen! Andrew wants to note that—despite the lede—no actual buckets of money are involved ... although he's not averse to some if folk are feeling inclined that way.
- 31/03/2013: Congratulations to Alessandro Fedrizzi and former QT Lab Alumnus Kevin Resch for their paper in Nature Photonics, Spectral compression of single photons. Very nice!

Matt's coauthors include much-missed QT Lab alumni Marco Barbieri and Nathan Langford, and the paper came out of a research trip to Ian Walmsley's wonderful group in Oxford. Congratulations one and all!
- 08/01/2013: Edwin Cartlidge has a thoughtful piece in Physics World today, 'Boson sampling' offers shortcut to quantum computing. Surf on over and have a read!

No need to choose, read them both!
- 21/12/2012: And the articles continue. Anna Salleh of ABC Science has written a nice article on our Science paper, Proving the need for quantum computers.
- 21/12/2012: And in the UK, Devin Powell has a nice News article in Nature that discusses the Oxford BosonSampling results, with a mention of ours in a sentence but a great photo of Matthew heading the article, Photon devices could outperform ordinary computers.
- 21/12/2012: Adrian Cho has written a great news article in Science that talks about our BosonSampling research, as well as that of our colleagues and friends in the UK, Austria, and Italy: New Form of Quantum Computation Promises Showdown With Ordinary Computers.
- 20/12/2012: Well that was quick! Jacob Aron of New Scientist has written an article about our and Oxford's Science papers, Victorian counting device gets speedy quantum makeover. (In it he has promoted Matthew to group leader: Andrew is quite happy with this as he plans to go back to the lab and let Matthew get on with the paperwork...)
- 20/12/2012: Eureka Alert has three photos for our BosonSampling paper:
○ The logo of the Quantum Technology Lab spelled out with the laser beams used in the BosonSampling device.

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!

- 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!
