Congratulations to Greg on this nice interview with Pop Physics, where he explains his fascination with quantum optics and his gripes about the long hours and low pay!
(For a somewhat less qualifiedly positive perspective on graduate school, but echoing many of Greg's themes, this recent essay is worth a glance.)

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.
