German scientists have managed to get cesium atoms in a state called a quantum walk, basically a superposition of all the possible states of particle, according to the article. From the article: "Quantum walks were first proposed by physicist Richard Feynman and are, in terms of probability, the opposite of a random walk. A random walk might be modeled by a person flipping a coin, and for each flip he steps left for heads and right for tails. In this case, his most probable location is the center, with the probability distribution tapering off in either direction. A quantum walk involves the use of internal states and superpositions, and results in the hypothetical person "exploring" every possible position simultaneously."
