01/01/2014: Happy New Year! For those of you who like round-number anniversaries, 2014 is a significant year for quantum information.
○ 50 years ago John Bell published his famous inequality paper,
○ 30 years ago quantum cryptography was invented by Bennett and Brassard,
○ 20 years ago—after a long gestation—quantum computing was born with Peter Shor's paper introducing a fast factoring algorithm.

22/05/2013: There's a nice article at FQXI Discord in the Quantum World that mentions—amongst many other things—our experimental work on quantum discord. Surf on over and have a read!
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!
27/03/2013: Andrew is one of twenty new Fellows of the Australian Academy of Sciences, five of whom are from UQ. He's very thrilled and very humbled.

15/01/2013: Congratulations to Matthew Broome for his paper in Nature Communications today, Multiphoton quantum interference in a multiport integrated photonic device. 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.

22/10/2012: Congratulations to Marcelo Almeida, whose paper on Estimation of a quantum interaction parameter using weak measurements: Theory and experiment was published today in Physical Review A. Co-authors included QT Lab Alumni Marco Barbieri and Michael Goggin, and the oft-visited Holger Hofmann: a shame we can't all celebrate in the same room today!

Congratulations to joint first-authors Matthew Broome and Takuya Kitagawa, and everyone in both the UQ and Harvard teams!
