Old news from the Steinberg group

"Old news" from the Steinberg Group



Just a reverse chronological list of some of our old stories of potential interest -- sorry for the lack of formatting.

Congratulations to Alex on winning one of the prestigious new Banting Postdoctoral Fellowships (along with the equally prestigious Rothschild Fellowship, and the growing-in-stature CQIQC Prize Postdoctoral Fellowship)!

Sven and Alessandro's paper (with Andrew White & myself) on matchgate quantum computing has been selected one of the New Journal of Physics's "Best of 2010". Congratulations, guys!

Congratulations to Chris on passing his SGS defense! Yet another doctor in the family!

Our paper on closed timelike curves has finally appeared in PRL!

Congratulations to Chris on passing his departmental oral!

Samansa has passed her SGS Ph.D. defence! Congratulations, Samansa!

Congratulations on passing your SGS oral, Herr Doktor Mirko!

Justin Mullins's "The Quantum Time Machine" discusses our work with Seth Lloyd and Lorenzo Maccone on closed timelike curves in the 17 November 2010 issue of New Scientist.

Samansa's PRL on doing pump-probe spectroscopy of vibrational states in an optical lattice has been published!

Samansa has passed her departmental thesis defense - congratulations!

Krister has passed his SGS oral -- congratulations, Krister!

Samansa's paper on 2D spectroscopy of the lattice has been finally accepted at PRL!

Both Mirco and Krister have passed their departmental thesis defenses!

Unlike the referees, wired.com and slashdot seem to find our paper on closed timelike loops interesting!

After a two-year struggle, Rob's paper on MUB-based tomography has finally been published!

Krister seems to be hogging the news lately, but deserves congratulations on his latest demonstration that his remarkable talents extend way beyond experimental physics (spontaneous parametric down-conversion and quantum imaging explained through dance).

Congratulations, Dylan, on winning a PGS-D fellowship!

Congratulations, Krister, on following up your CIFAR fellowship news with the award of an NSERC postdoctoral fellowship!

Congratulations, Krister, on winning a fellowship to be a postdoctoral member of the CIFAR Junior Academy!

Congratulations, Rob, on becoming an Assistant Professor at Dalhousie! (With Ana -- UNC-Charlotte -- and Kevin -- IQC-Waterloo -- this makes 3 former students from our group in faculty positions, with a combined salary probably equalling that of our former student at ScotiaBank...)

Congratulations to Krister on his virtuoso public lecture on "The Quantum Physics of Harry Potter"!


Alain Aspect awards the inaugural John Stewart Bell Prize to Nicolas Gisin on behalf of the CQIQC in August 2009!

Jeff's weak-measurement paper inspires this article in the Toronto Star, which goes a long way towards making Hardy's Paradox accessible through pithy (if not always accurate) observations like "Perhaps anti-photons are the smallest particles of darkness, and if you put a lot of them together you get a black hole or some other matter-destroying device. For example, Bernie Madoff. Anyway, photons apparently go around in pairs due to a process called Quantum Entanglement, which I think is like a dating service for very small (and presumably lonely) particles."

March 5th: Jeff's weak-measurement paper is discussed in this article in The Economist!

Jeff's paper on using experimental joint weak measurements to resolve Hardy's Paradox has appeared in Phys. Rev. Lett. 102, 020404 (2009).
Here is a lay description of our work on Hardy's Paradox.

Krister and Rob's paper on triphoton tomography has appeared in Nature 457, 67 (2009).

Mapping a New World For Light: The scientific revolution is often dated back to Copernicus's model of the solar system and before that, the re-recognition by the Western world that the Earth is round. Yet in the strange domain of quantum physics, scientists have once more been studying a flat world for the past several years. Our latest result, published in Nature on January 1st, 2009, has now shown what riches can be found by circumnavigating the quantum globe.

Rob and Pete's theory paper on tomography of practically indistinguishable systems has appeared in Phys. Rev. A

Chinese test two missiles at Mt. St.-Louis in Ontario
Samansa's paper on pulse echoes in the optical lattice has been selected for publication in the Virtual Journal of Nanoscale Science & Technology, as well as the Virtual Journal of Quantum Information.

Max & Rob's article on nonorthogonal-state discrimination, Phys Rev A 76, 062314 (2007), was selected for the Virtual Journal of Quantum Information.

"Two Slits Are Better Than One!" at sciencebase.com describes our recent experiment on the complementarity principle (see also New J. Phys. 9 (2007) 287 for our article). Our paper is also the "featured journal article" in the Sep 2007 edition of PhysicsWorld.com

Breaking News: Relativity Still Correct! Photon tunneling hits the news again every 5 or 10 years, as those who would over-dramatize it hope for more and more of the voices of reason to get tired of commenting on the same experiments (e.g. my 1994 thesis). New Scientist covers the latest hype in the August 17, 2007 issue, also picked up by photonics.com and many media outlets which were too gullible to be cited here :-)
[Here I'll point out that even the relatively (no pun intended) even-handed coverage quoted me as saying "it's just a matter of interpretation," where what I am rather sure I said was "I take no issue with their experimental results, only with their interpretation." What I meant of course is that their interpretation is wrong: not that one is free to interpret their experiment as violating relativity or not!]

An Einstein-year Photon Symposium on Nov 16-17, 2005!

Dürrenmatt's THE PHYSICISTS May 13-14 at St. Vladimir Theatre in honour of the Year of Physics!

Institute of Physics Highlights of 2004 lists "pure and applied quantum physics" as the top story, including references to our 3-photon path-entangled state and the related 4-photon state created by our friends in Vienna (including our alum Kevin Resch).

New Scientist article on our 3-photon entangled state.

Physics News Update recently featured work by our alum Naomi Ginsberg.

They also recently described the one-atom laser built by our alum Jason McKeever.

In 2001, they featured our work showing that single-photon counters can be used to probe not just the number of photons, but also their quantum-statistical properties.
