    Experimental sketch: Rubidium atoms are captured by laser beams (red). Another additional laser (blue) excites about half of the atoms to such an extent that their atomic shells merge with the adjacent atoms.

    New record with entangled quantum bits. Dead or alive, left-spinning or right-spinning – in the quantum world particles such as the famous analogy of Schrödinger’s cat can be all these things at the same time. An international team, together with experts from Forschungszentrum Jülich, have now succeeded in transforming 20 entangled quantum bits into such a state of superposition. The generation of such atomic Schrödinger cat states is regarded as an important step in the development of quantum computers.
