Cirac and Zoller win the Wolf Prize for physics
Ignacio Cirac and Peter Zoller were just announced as winners of the 2013 Wolf Prize for physics. I’m not sure if this is the official citation, but the Jerusalem Post is saying the prize is: for groundbreaking theoretical contributions to quantum … Continue reading

Apocalypses, Firewalls, and Boltzmann Brains
Last week’s plebeian scaremongering about the world ending at the wraparound of the Mayan calendar did not distract sophisticated readers of grqc and quantph from a more arcane problem, the socalled Firewall Question. This concerns what happens to Alice when … Continue reading

21 = 3 * 7
…with high probability. That joke was recycled, and in recent work, Bristol experimentalists have found a way to recycle photonic qubits to perform Shor’s algorithm using only qubits. (Ok, so actually is was Kitaev who figured this out, as they … Continue reading

Haroche and Wineland win Physics Nobel
The physics prize was shared between experimentalists Serge Haroche and David Wineland, longtime leaders in the study of atomphoton interaction. In recent decades both have honed their techniques to meet the challenges and opportunities opened by “quantum information science” which … Continue reading

Physics World gets high on Tel Aviv catnip
It should be no surprise that loose talk by scientists on tantalizing subjects like backward causality can impair the judgment of science writers working on a short deadline. A recent paper by Aharonov, Cohen, Grossman and Elitzur at Tel Aviv … Continue reading

Having it both ways
In one of Jorge Luis Borges’ historical fictions, an elderly Averroes, remarking on a misguided opinion of his youth, says that to be free of an error it is well to have professed it oneself. Something like this seems to … Continue reading
