Can quantum mechanical description of physical reality be considered complete?

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 […]

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 […]
