Vladan Vuletić and his colleagues at MIT and the University of Belgrade have succeeded in placing 3000 rubidium atoms in an optical cavity, cooling them to near absolute zero and then entangling their spins using just one photon. The feat could lead to better quantum measurements because it circumvents the Wigner function, which characterizes the probabilistic nature of quantum ensembles.
