That was the title of a ground-breaking article published in 1935 in the Physical Review by Einstein, Podolsky and Rosen (EPR). In this article they brought to the attention of physicists the strange correlations predicted by quantum mechanics for observations involving what are now called entangled systems. They used those predictions to argue that quantum […]

“Yes,” he said at last in rather a strained drawl. “I did have a question. Or rather, what I actually have is an Answer. I wanted to know what the Question was.” Prak nodded sympathetically, and Arthur relaxed a little. “It’s… well, it’s a long story,” he said, “but the Question I would like to […]
I have submitted a new paper to the physics arxiv, entitled “Experimental criteria for steering and the EPR paradox”. It is joint work with my collaborators Steve Jones, Howard Wiseman and Margaret Reid. I’m particularly excited about finally getting this paper off, as it was holding back a few other works — and because I […]
Yesterday, while giving a lecture on the philosophical implications of quantum mechanics, I was asked, for the second time in this kind of context: So is this quantum weirdness like the question: if a tree falls in the forest and there’s no one there to hear it, does it make a sound? So I think […]
Reading Scott Aaronson’s blog, I came across this series of lecture notes, and at the start of the first lecure there was this nice introduction to his grade system. Scott is really a great mind. His grade system reflects a deep understanding of quantum mechanics. I know, I know, grade systems talk about students, and […]
