WE MAY soon be able to watch the spooky workings of quantum mechanics with our own eyes. Nicolas Brunner of the University of Geneva, Switzerland, and his colleagues wanted to find out whether human eyes could see the signs of entanglement – a quantum property that allows two particles to become inextricably linked so that making a measurement on one instantaneously affects its partner, no matter how far apart they are. The effect can demonstrated in a simple experiment. A pair of entangled photons, A and B, are generated and then sent along different paths. Each photon meets a beam splitter,
